| Abstract: | The Noise Equivalent Temperature Difference(NETD)is a main function parameter of infrared imaging systems.This text mainly analyzed Spatial Noise Equivalent Temperature Difference(S-NETD),and compared the results of Temporal Noise Equivalent Temperature Difference(T-NETD)and S-NETD.Based on the measurement and data analysis of ETD,this paper suggested the great influence of spatial-NETD on the evaluation of infrared imaging system.A suggestion of measurement was proposed. |
