Abstract
This paper describes a new test bench for measuring the modulation transfer function of an infrared focal plane array. The system is based on the use of a plane target made with a continuously self-imaging grating (CSIG) that projects in polychromatic light a biperiodic pattern of small and non-diffracting spots called a nondiffracting array.
