Introduction to infrared thermography

What is thermography and how can we use it?

An introduction to the technology and some important applications for it.



Objectives

• Know how to define infrared thermography• Understand the subtopics that make up infrared

thermography• Understand the importance of temperature as a

control parameter• Understand what makes thermography unique

and useful• Be able to recall some examples of applications

for infrared thermography

Why is temperature important?

• Name some processes – industrial or otherwise, where temperature is important. Why?

• Name ONE process where temperature is completely unimportant…



What makes thermography so useful?

• It is non-contact – uses remote sensing– Keeps the user out of danger– Does not intrude upon or affect the target at all

• It is two-dimensional– Comparison between areas of the target is possible– The image allows for excellent overview of the target– Thermal patterns can be visualised for analysis

• It is real time– Enables very fast scanning of stationary targets– Enables capture of fast moving targets– Enables capture of fast changing thermal patterns
