Abstract
Noise Equivalent Temperature Difference (NETD) is one of the signs of infrared thermal imaging system performance index. In this paper, Spatial Noise Equivalent Temperature Difference (S-NETD) was studied, the testing technology of S-NETD was improved, the test results were compared, and the importance of the test of S-NETD was pointed out. The basis for the application of S-NETD in the thermal imager performance test is provided.
