Paper Abstract

The evaluation of technological parameters is of primary importance for the detector industry, since it allows both to validate the fabrication process and to optimize the electro-optical characteristics of the detectors. By measuring the spectral response of detectors with a high resolution, it is possible to display specific optical effects. Using a radiometric model of the detecting architecture, we are able to understand their physical origins and to determinate some technological and optical parameters. We have developed a test bench which provides spectral responses of infrared detectors using a Fourier transform spectrometer. The principle of the test bench and the methodology used are detailed. Experimental results, as well as the associated radiometric model, are presented for a dedicated 320×240 MCT LWIR focal plane arrays (FPAs).
