Application of Surface Antireflection Treating in Infrared Thermal Wave Nondestructive Testing

The application of surface antireflection technique in infrared thermal wave nondestructive testing is presented. The method for covering antireflection membrane on the specimen surface by vacuum-pumping has been tested. The experimental results show that this technique is effective for enhancing sample surface absorption and emissivity, moreover, it does not stain or damage the specimen.
