How human « see » heat

ß Temperature

• Visible spectra for human eye

(4)

Infrared thermography

• Optical measurement

• IR sensors for “low” temperatures

• Interests:

• Ability to capture information not accessible to human eye • Without contact

• Quickly

(5)

Infrared thermography

• Applications: civil engineering, military, security, marine,

(6)

Materials inspection

• Transport industry (aviation, automotive, spatial, marine)

• Principle:

• disturb and look at consequences !

• 2 ways

• In order to reveal internal defects and damage processes

1/ Heating-Lighting (Non Destructive Testing)

2/ Mechanical load (Damage monitoring)

1/ Non Destructive Testing

• Analysis of bonded repaired composites (Barus Ph.D. 2016)
