红外热成象是非接触、建立在温度基础的检测物体的质量、内部状态、结构或缺陷的一种方法。国外十分重视红外热象无损检测,美国、苏联、日本等在六十年代中期就开始着手研究,应用范围包括多层复合材料、蜂窝结构、发动机叶片、导弹固态燃料与包复层间的检测等。我国虽然起步较晚,但近年来在工 Infrared thermal imaging is a non-contact, based on the temperature of the object to detect the quality, internal state, structure or defect of a method. Foreign countries attach great importance to the non-destructive testing of infrared thermal images. The United States, the Soviet Union and Japan began to study in the mid-1960s. Applications include testing of multi-layer composite materials, honeycomb structures, engine blades, missile solid fuel and cladding cladding . Although our country started late, it is working in recent years
