Abstract

System level modeling and testing of SWIR, MWIR and LWIR infrared cameras are presented. Automated camera testing is performed by Santa Barbara Infrared's IRWindows software. Some of the standard tests are NETD, MTF, 3D noise, and Ensquared Energy. An Excel spreadsheet has been developed to model camera system performance which allows relatively easy addition of new camera types. Each camera type includes information on the ROIC (number and format of pixels, pixel readout rate, pixel size, well size, read noise), sensor material (spectral QE, fill factor, dark current vs temperature), lens, window and warm filter spectral transmission, cold filter temperature and spectral transmission, and cold aperture configuration (diameter and distance from sensor). Atmospheric temperature, turbulence, spectral absorption and spectral emission are included in the Excel model.
