Simulation research of infrared image detection technology for halogen lamp heating

For infrared imaging nondestructive testing (NDT) of composite materials,using a halogen lamp as an excitation source,the detection system with uncool thermal infrared imager was built.Test pieces of carbon fiber composite material with flat hole were simulated and analyzed by Ansys software,and detection parameters of the system and test results were obtained.The actual test pieces of carbon fiber composite material with flat holes were tested by the system.The results show that the simulation analysis is consistent with the actual test results.This system has the characteristics of low cost,good detection effect,easy adjustment of excitation power and operation time,and it can be applied to non-destructive testing of various types of composite materials.
