Thermography using Roboti c ScannerThermography using Roboti c Scanner

• Robotic scann er accommodating thermographic equipment

for testing of composite samples using:

• Transient Thermography

• Near Infrared Thermography

• Fulfills objective of reducing the use of subjective manual

inspections leading to in creased ‘Probability of detection’ at

a higher confidenc e level
