摘要： Noise Equivalent Temperature Difference is a key point for the evaluation of IR detectors and imaging systems. Our theoretical model of temporal noise predicts the NETD and responsivity of detectors with an accuracy better than 3 mK and 5%, respectively in a large range of scene temperatures and integration times. This study clearly shows that we are able to estimate the temporal noise in any configuration and particularly for scene temperatures riot easily accessible in standard laboratory conditions. Also, we can measure the amplitude of different noise contributions (1/f, white noise) and the FPA leakage current.
