Heat Stimulating Methods in Thermography of Airplane Composite

Effective heat stimulating is an important factor to gain good result in active infrared test. Based on analysis of exiting heat stimulating methods and practical application, this paper proposed the heat stimulating method applicable for field test. Combined with development of thermography system for airplane composite, the significance and affecting factors of heat stimulating by pulse light or heat radiation were analyzed in detail. Finally, some suggestions about configuration design of heat stimulating lamphouse were put forward.
