I. SYSTEM CONTROL APPLICATION (SCA)

SOFTWARE OVERVIEW

Getting started

The main SCA software idea is to provide the ability to control different technological

processes and their sequences. Main SCA software advantage is the ability to integrate and

control various hardware (different manufacturers) using unified technological parameter

systems. SCA software supports following hardware:

Linear stages from Aerotech Co. Ltd. (For example ALS130-150 XY with

NLdrive/Npaq controllers).

Rotary stages from Aerotech Co.Ltd.

Aerotech stages must be controlled by A3200 controller.

Galvo scanners (GSI Group, Inc.; ScanLab AG) controlled through RTC4 or

RTC ScanAlone (ScanLab AG) interface board via XY100 protocol.

Pjezo actuators from Physik Instrumente (PI) GmbH & Co. (For Ex.: P-725 with

E-750 controller).

Motorized attenuators (Altechna).

Polarization rotators (Altechna).

Other devices.

This paper describes SCA software fabrication algorithm, programming aspects, program

GUI (Graphical User Interface) and hardware configuration wizard. SCA software

requires different computer programming knowledge for particular operation:

1 level (highest knowledge) – creating, editing and updating fabrication ―letters‖ using

C++, Delphi, C#.

2 level – fabrication algorithm construction from ―letters‖, ―words‖ or ―sentences‖ created

earlier, simple fabrication algorithm creation and hardware configuration (requires

knowledge in hardware used).

3 level – load saved fabrication and hardware parameters - requires only basic PC

knowledge.

Orientation Tab


Copyright 024

Device selection. It is forbidden to select different devices if you do not have galvo

scanners synchronization with stages.

Select Scan direction. If fabricating with stages, it is recommended to scan with

upper axis (usually Y) – less mass moved.

Mark Type Tab

In the Mark Type Tab you can adjust bitmap marking properties, such as

Grayscale 2D mode – enable grayscale mode (described in grayscale mode section)

Optimization – scan algorithm optimization - skip empty pixels by executing fast jumps.

Mark on fly – fabricate with galvo mirrors and linear stages simultaneously in „on-fly―

mode.

Grayscale 1D Height mode

mm per color bit – describes height difference between pixels with different color bit. For

example if for some pixel color bit = 50 and ―mm per color bit‖ = 0,01 mm/bit , then Z

will move by 0,1 mm to fabricate current pixel.


Copyright 025

Speed – Bitmap fabrication speed [mm/s].

Pixel frequency – pixel mark frequency [steps per second] – speed dependent.

Steps per pixel – pixel multiplexing. Step per pixel number must have integer square root,

for example: 1, 4, 9, 16...

Pulses per step – pulses per pixel (step).

Repetition – bitmap fabrication repetition.

Line Jump Delay – delay after each bitmap line. Minimize vibrations occurring if axis is

still settling down.

Grayscale Mode

Allows to fabricate grayscale bitmaps, there each pixel is determined with different

amount of pulses or at different height according to the color depth (256 bit). Fabrication is

done step-by-step.


Copyright 026

Color bit range – 256 bit grey scale loaded bitmap color bit selection. For example if

range is from 100 to 256, then it will fabricate only pixels with color value >100:

Steps per pixel - pixel multiplexing. Step per pixel number must have integer square root,

for example: 1, 4, 9, 16...

Jump speed – jump speed between pixels and lines.

Line jump delay – delay after line jump for stages to settle down.

Pixel jump delay – delay after pixel jump for stages to settle down.

Pixel modes:

1. Pulse

a. Pulses per color bit – describes triggering pulses amount per bit color. Stages do not

start moving, until curtain pixel is done. If Pulses per color bit = 50, and if pixel color is =

256, then 50 x 256 = 12800 pulses per certain pixel. This value can be defined as linear or

using an expression (e.g. 2*per_color_bit, per_color_bit*per_color_bit).


Copyright 027

2. Height

a. mm per color bit – describes height difference between pixels with different color bit.

For example if for some pixel color bit = 50 and ―mm per color bit‖ = 0,01 mm/bit , then Z

will move by 0,1 mm to fabricate current pixel.

b. Pulses per pixel – describes triggering pulses amount per pixel.

3. Rotation

a. Pulses per pixel – describes triggering pulses amount per pixel.

b. Deg per color bit – pixel color depth dependent rotation (same as mm per color bit,

only in degrees).

c. Start angle – start angle in degrees.

Bitmap Hexagonal Mode (BHM)

To enable Hexagonal mode in the Bitmap properties window go to: Tools =>

HEX. Picture matrix will be converted 1:1 => 1:2 and stretch factor will be automatically

set to to fit to hex cell:

Hex mode works both with normal and grayscale mode.

PLT/DXF sorting

PLT and DXF commands allow user to sort file entities

(lines, polylines, arcs…) and therefore optimize

fabrication (time is saved by removing unnecessary

jumps). Sorting puts elements in order by comparing

distance between entities. Fabrication order options incline sorting with Top down or

Bottom up priorities (higher or lower layers are fabricated earlier).

IV . FABRICATION ALGORITHM COMMANDS

To change fabrication algorithm command parameters select it - depending on

the selected command, the different parameters you will be able to change in

the command parameters and description table.

Note: some commands are available only when certain hardware is enabled.

VAR – define variables. For Ex.: a = 5; b = a+5; radius = 12 … For

more information check Variables and Mathematical expressions

section.

ZT – move only Z axis without firing.

XYZ

o Jump – move XYZ linear stages asynchronously to a certain

specified point with laser turned off.

o Constant density – fabricate using XYZ linear stages with

fixed laser pulse density = jjstage movement in a specified line

by triggering laser pulses which have even distribution in SPACE. Program

automatically calculates margins* which are required for stages to

accelerate to a certain velocity. Laser

triggering signals are generated

synchronously with the stage position.

* To enable margins choose:

Setback or Leave Margin for

acceleration margin.

Return or Leave Margin for deceleration margin.

If margin is ‗None‘, stages accelerate/decelerate during fabrication/movement.


Copyright 029

Example:

o Constant frequency – fabricate using XYZ stages with fixed laser pulse

frequency = stage movement in a specified line with triggered laser pulses

which have even distribution in TIME. Program automatically calculates

margins which are required for stages to accelerate to a certain velocity.

ARCT – X and Y stages synchronous movement in an arc trajectory with laser

turned off.

ARCD – X and Y stages synchronous movement in an arc trajectory by triggering

laser control pulses which have even distribution in space. Laser triggering signals

are generated synchronously with the stage position.

ARCF – X and Y stages synchronous movement in an arc trajectory by triggering

laser control pulses which have even distribution in time.

Direction – Clockwise/ Counter Clockwise

R – arc radius [mm]

φ1 – start angle [deg]

φ2 – stop angle [deg]

If Acceleration SetBack and

Deceleration Return selected,

then:

1) Sets back for acceleration

2) Accelerates

3) Move at constant velocity

4) Brakes

5) Returns

If Acceleration LeaveMargin

and Deceleration LeaveMargin

selected, then:

1) Accelerates

2) Moves at constant velocity

3) Decelerates


Copyright 030

Circle – Fabricate a CIRCLE at constant density or frequency mode = X and Y

stages synchronous movement in a circle trajectory by triggering control laser

pulses which have even distribution in space or time. In density mode laser

triggering signals are generated synchronously with the stage position.

Initial point – circle position in respect to initial

position: 1.Top 2. Centre 3. Left 4. Right 5. Bottom.

Note that if center point is selected, stages will firstly

move to point 4 and then will fabricate circle in CW

direction.

Radius (R) – circle radius [mm]

Repeat – Number of times to repeat circle fabrication.

Point – Shoot number of laser pulses to a point (Device – stage or galvo).

CS/CF – Cycle start/finish. Every CS command requires CF command.

Transform – Rotates vectorical images by X, Y, Z axes.

Bitmap – linear stage or galvo mirror motion in trajectory specified by BMP, JPG

or GIF bitmap files (recommended - 1 bit). Ability to fabricate with galvo mirrors

and linear stages simultaneously in „on-fly― mode.

Bitmap picture fabrication function features several operation options:

Black and white picture

Regular marking of black and white pictures is supported by devices controlled

through A3200 and RTC4 controllers.

Grayscale picture

(Grayscale 2D, Pixel mode: Pulse) Number of laser pulses is changed according to

pixel‘s grayscale level. This function is supported by devices controlled through

A3200.

(Grayscale 2D, Pixel mode: Height) Z position of an object (or focal spot) is

changed according to pixel‘s grayscale level (pulses are deposited within different

Z altitude). This function is supported by devices controlled through A3200 on

systems having incorporated Z axis.

(Grayscale 2D, Pixel mode: Rotation) Beam polarization is changed according to

pixel‘s grayscale level (polarization is rotated using a rotational axis). This function

is supported by devices controlled through A3200 and systems having incorporated

rotational axis.

(Grayscale 1D Height mode) Z position of an object (or focal spot) is changed for

each individual line of the bitmap picture according to first pixel‘s grayscale level


Copyright 031

(pulses are deposited within different Z altitude). This function is supported by

devices controlled through A3200 on systems having incorporated Z axis.

GCode – Allows to import G-code from file (or from direct user input) to

fabrication algorithm. This command can alter jump and mark speeds in file. E.g.

G-code line: ‗G01 X1 F20‘ with ‗Alter mark speed‘ enabled and set to 50 will

change this line to ‗G01 X1 F50‘ (changing speed from 20 to 50). G-code

command in reading from file mode always returns to start position (in direct input

mode user can choose not to return to start position if SCA has recognized all typed

commands).

Attenuator

o Attenuator command with settings: Target power + ―One step mode‖.

This regime allows to control attenuator‘s position according to power

meter readings.

Attenuator and power meter must be connected to system.

o Attenuator command with settings: Target power

―Target power‖ [W] – power value to be reached;

―Range‖ [W] – after reaching power within this range, execution of

command is finished.

―Use calibration table‖ – when selected, attenuator will be regulated

according to values in calibration table.

LaserRunStop – Set Laser state and Fire trigger state. Laser state can be set to

Run or Stop. Fire trigger state has four states: Positive Pulse, Negative Pulse,

be deactivated (add "Galvo drill" and uncheck "Active"). Next a new Galvo drill

command with required movement could be added.

Galvo and stages synchronization

During "Galvo drill" operation (till "Galvo drill"

deactivation) stages could perform movement.

This type of operation could produce thick laser

line made by stage movement trajectory. Laser

line thickness controlled by "Amplitude" parameter in "Galvo drill command". If

"Laser ON" is checked, the laser fire signal is emitted at a default laser frequency,

otherwise the galvo scanners will produce

only movement and the laser output should

be controlled by stage commands (ex.

Settings form

Settings form allows defining various camera parameters.

In General page a camera name and settings file location can be defined. If laser beam

position is outside camera view, a ―Camera view position fixed‖ must be checked.

In Camera settings page a camera parameters

can be defined.

Camera calibration

To run camera Field calibration tool press:

Tools => Machine vision => Field

calibration


Copyright 058

Firstly, to have a proper camera coordinates calibration with laser coordinates, camera x

and y axes must match with stages axes. To rotate camera image, check "Rotate" in

Camera settings page. Image also could be flipped vertically or horizontally by checking

"Flip horizontally" or "Flip vertically" in Camera settings page.

A sample must be put in fabrication position and laser focus must be found. Laser focus Z

must be entered in "Fabrication position" z coordinate manually or by "Set current

coordinates" click if current position is laser focus position. "Camera view position" is

used if camera view position is fixed in relation with the laser beam position. "Camera

view position" approximately allows specifying the distance between laser beam position

and camera view position. These coordinates can be found by any engraved structure in

(0;0) coordinates. The structure should be moved to the view center. The shift coordinates

should be entered as "Camera view position". Calibration is based on finding coordinantes

of two fabricated points. Point size is defined in "Laser spot size" field. Point size in

camera view must be at least fiew pixels to have a correct detection result. Detection of

point is based on background image, so firstly background image must be taken by

"Capture background" click. If an image is too dark or too bright, correct camera exposure

time. Next, first point can be fabricated by "Fabricate point 1" click. Finally, "Find point

1" can be clicked. If no point will be found, repeat "Fabricate point 1" and "Find point 1".

After first point will be found, set distance between two points in "Step size" field. Second

point must be in same view, but as far as posible from first point to get accurate

calibration. Do same steps "Capture background", "Fabricate point 2", "Find point 2" to


Copyright 059

get second point position. After all points will be found, press "Calculate calibration

settings" and "Set calibration settings". The image should appear in correct position.

Camera focus

To run camera Find focus tool press:

Tools => Machine vision => Find focus

Camera focus form is used to find camera focus position. Find position can be defined

with virtual joystick. Scan is started at

"Camera focus Z" minus "Object height" and

minus "Scan range". Scan is finished at

"Camera focus Z" minus "Object height" and

plus "Scan range". To scan only small area,

press "Set focus find area" and using left

mouse key press on top left area corner and

with left mouse key press on bottom right area

corner. Area which is out of range will apear

in different color. To reset find focus area,

press "Reset focus area". The focus Z position

is set to global variable gCAM1FZ (if camera

is first) or gCAM2FZ (if camera is second)

Sample tilting detection

To run Sample tilting detection tool press:

Tools => Machine vision => Sample tilting detection

Sample tilt detection is based on coordinate detection of three points on the sample. To get

accurate results, three points must be as far as possible from each other.

Sample tilt can be detected with auto focus device or camera. Both devices are used to

search best focus Z positions of

three points. Points can be

entered manually or by "Go to

point1", "Go to point2", "Go to

point3" buttons click. The

button click invokes the virtual

joystick, which can be used to

shift sample to required

position. "Find focus" buttons

runs a find camera focus or auto

focus find forms based on

selected device. After focus is

found and focus find form is


Copyright 060

closed best focus Z position is entered in searching point z coordinate.

―Refind‖ button allows automatically refind focus in all three points if focus find device is

camera. After all three points found, press "Calculate" button. Sample degrees in X and Y

axes are calculated from three points and values set to global variables: gtx, gty.

Object position detection

To run Sample position detection tool press:

Tools => Machine vision => Sample position detection

Object position detection is based on background subtraction, so first step is to take the

background. When the background is taken, object can be placed in camera view position.

Press ―Detect‖ button to detect object center and angle. ―Set global variables‖ button

allows to set detected values to global variables gCAM1OX, gCAM1OY, gCAM1OA (if

camera is first) or gCAM2OX, gCAM2OY, gCAM2OA (if camera is second)
