Paper Abstract

A test bench for measuring the Modulation Transfer Function of an InfraRed Focal Plane Array (IRFPA) is described. The system is based on the use of the self-imaging property of a periodic target made of thin slits for a direct projection of a high-resolution pattern directly on to the tested sensor. The test bench has furnished two different types of experimental results on a specific IRFPA. On one hand, a global method called Canted Periodic Target Test has been developed and applied leading to MTF evaluation up to five times the Nyquist frequency. On the other hand, a local line scanning of every pixel has been made.
