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.
