UNDERWATER LASER SCANNING
NEWTON LABS
1
NEWTON LABS
Established in Cambridge, Massachusetts in 1990 as an offshoot of the Massachusetts
Institute of Technology (M.I.T.); moved to Seattle in 1995
Specializes in machine vision including line laser scanning, optical automation and robotics
with an emphasis on Automation…“Machines that can See and Make Decisions”
Many of Newton’s projects are the first-of-their-kind in the world
Newton internally manufactures all scanning, machine vision and robotics software and
hardware, including controllers, cameras, lighting, electronics, machine control and
mechanics.
The first Newton Underwater Laser Scanner was the NM200UW developed in partnership
with Exelon, a major U.S. nuclear utility; specifically designed to operate underwater in-
vessel in either PWR or BWR nuclear plants.

Some comparisons with air scanning:
Limited Range-for practical purposes 10 Feet (3 Meters)
Very high resolutions can be produced
Water clarity is important
The Scanner must be held still during the scan for accurate measurements-often more
difficult underwater

Crack Detection and Measurement
Surface Scanning-
Human Viewable High Resolution pictures matched to the scan
Measurement – From CAD Models
UNDERWATER LASER SCANNING
5
Feature Identification and Measurement
Complete CAD models- With multiple scans
UNDERWATER LASER SCANNING
Generally has the same constraints as in air scanning
Newton Scanners produce higher resolutions than most in-air scanners
6
Models:
Functional from 6 Inches (150mm) to 10 Feet (3 Meters)
Depths to 6,000 Ft (2000 Meters)
Resolutions to less than .001 (0.025mm)
Internal Pipe Scanning
Internal Tank Scanning
Models specifically designed for use in nuclear facilities-both from allowed
materials and ease of decontamination
NEWTON PRODUCES VARIOUS MODELS OF
UNDERWATER LASER SCANNERS

NEWTON UNDERWATER LASER SCANNERS
Uses Line Laser technology coupled with a very high resolution camera
8
NEWTON UNDERWATER LASER SCANNERS
All models fully sealed-no moving parts exposed to the water
All models produce high-resolution human viewable pictures along with the scan for ease
of set-up, alignment and human analysis of the scanned object
All cables and connectors rated to 6,000 PSI
Minimum size for rated capabilities
Designed for many mounting methods
Robots
Poles
ROVs
Arms
Communication between the head and controller via GigEthernet
All Head power supplied through the cable from the controller-no other connection to the
head required
Machined Photogrammetry targets on the outer surface

M300UW UNDERWATER LASER SCANNER
Operate with an effective scanning distance of between 1.5 feet (0.46 m) and 10 feet (3 m)
from the target surface
Able to scan an area 9 feet by 7 feet(2.80 m by 2.08 m) with an accuracy of +/-1.0 mils
(0.025mm).
Waterproof to a depth of 320 ft. (100 m)
In addition point cloud data output, there is a human-readable video interface on the
console which displays the scanned area in real time
