Abstract

Considering the demand of performance test of infrared spectral imaging equipment, as the key indicator, the 3-D noise model of noise equivalent temperature difference is analyzed. The seven components and their meanings are presented. A test algorithm based on standard deviation of NETD is put forward. The paper shows the composing and principle of the detection system, and introduces the computational procedure and detection process of NETD. The test algorithm is verified by experiments. According to the comparison with the imported equipment, the test results have good duplication and high precision. The test system has been applied to the performance test for several kinds of infrared spectral imaging equipment, which meets the demand of engineering support.
