Focal-plane array testing
(under development sep 13)
Focal Plane Array testing (FPA testing) is the test engineering process of validation and verification of focal plane array imaging devices (unit under test UUT) at various levels of the development and/or production assembly process.
Overview
FPA testing (automated and semi-automated) utilizes hardware and software to characterize the UUT by measuring parameters such as: Signal Transfer Function; Signal Transfer Function against differential Temperature; Spatial Noise Power Spectral Density; Noise Equivalent Temperature Difference; Modulation Transfer Function; RMS and fixed pattern noise; Responsivity and detectivity; Spectral response; Crosstalk; Temporal noise; Fixed pattern noise; Minimum Resolvable Temperature Difference; Intensification gain; Field Of View; Spatial resolution; Dynamic range; Focus adjustment.
Software analyses the UUT sensor images in real time. Source temperature settings and target selection are computer-controlled. The software can integrate a complete test bench comprising collimator, source, optical table and data acquisition system.
