Paper Abstract

This paper reports studies on spatial characteristics of Mid Wave InfraRed (MWIR) InAs/GaSb superlattices (T2SL) photodetectors. Modulation Transfer Function (MTF) measurements on commercial T2SL MWIR Focal Plane Array (FPA) are reported, using a Continuously Self Imaging Grating (CSIG). We find that measurements of the pixel size can be reliably achieved thanks to a new approach of data processing. Next, a new class of radiometric characterization, called "correctability", or ability for FPA pixels to durably keep the same behavior when exposed to a given radiometric flux, has been investigated on. Gain and offset corrections and Residual Fixed Pattern Noise (RFPN) measurements have also been made. The results obtained confirm the potentiality of high performance T2SL infrared photodetectors.
