Abstract

The spatial response of a FPA is an important attribute of image quality. A novel test station for determining detector MTF has been developed and used on LWIR FPAs. The test station focuses an illuminated pinhole aperture onto a FPA, creating a sub-pixel spot. Total system MTF is determined by scanning the spot across the FPA. Optics MTF is measured by moving the imaged spot through focus and applying phase retrieval methods. The Optics MTF is then removed from the measured total MTF to produce the detector MTF. The technique has been applied to large area LWIR FPAs.
