Paper Abstract

Spectral response dispersion has a significant impact on the radiometric performances of infrared imaging system using detectors with a large amount of pixels. The main contributors of this dispersion are the detector itself, which contributes to the highest spatial dispersion, and the optical components and filters which contribute with smaller frequencies. This paper proposes a theoretical approach of the contribution of spectral response dispersion to the spatial noise, considering classical calibration methods with blackbodies. AEROSPATIALE has performed measurements of spectral response dispersion on large format 2D infrared detectors. The performances obtained taking into account these test results are given in order to identify the real weigh of spectral response dispersion effects on the infrared imaging system.
