BIRD - Universal Electro-Optic Test Bench For IR Detectors Calibration and test of IRFPA detectors: - Noise tests: fixed pattern noise, temporal noise, NETD responsivity, detectivity, 3D-noise, 2D-detectivity, - Dynamic range, linearity, - Non-uniformity correction, - Bad pixel localisation, - Spectral response, - Crosstalk, MTF. Designed for exhaustive testing of IRFPA detectors The BIRD210 bench consists of an electronic cabinet equipped with a set of ultra-low noise electronics including a clock signal generator, a bias voltage unit and a high frequency analogue to digital converter. An optical bench illuminates the detector under test with accurate and calibrated optical signals: a low temperature uniform and highly stabilized IR reference source for noise measurements, NUC and bad pixel tests, an adjustable IR source with high spectral resolution for spectral response measurements and an aberration-free pinhole or thin slit source for MTF and crosstalk tests. The BIRD software has the following features: - User–friendly interface for clock signal design, pixel remapping, bias voltage settings and A/D parameter definition and application of these parameters and signals to the detector, - Setting of parameters for testing functions such as temperatures for noise measurement and NUC, criteria for bad pixel localisation (up to 6 criteria), spectral range for spectral response analysis, etc. - Automatic control of the opto-mechanical elements of the optical bench (translation stages, blackbodies, monochromator) depending on the selected functions and the corresponding settings,
