Abstract

A method is presented for measuring the modulation transfer function of SPRITE detectors with a HgCdTe composition optimized for the 3-5 micron band. This method incorporates a 3.39-micron HeNe laser to generate Young's fringes of varying spatial frequency, which are scanned across the detector elements. The results are consistent with theoretical models for these devices and indicate a limited resolution capability for SPRITEs used for the 3-5 micron band.
