:Cold shield is an important part of IR detector,and the extinction quality of its inner wall directly affects the background noise,dynamic range and response uniformity of IR detector.Using several blackening processes of cold shield,flat samples were prepared.The average BRDF in 2 ~14μm infrared waveband was tested.According to test results,the characteristics of several techniques and practical application effects were analyzed,which provide the constructive suggestions for the design of cold shield inner wall of IR detector in different wavebands.
