Abstract
Modulation transfer function (MTF) is the ability of an imaging system to faithfully image a given object. The MTF of an imaging system quantifies the ability of the system to resolve or transfer spatial frequencies. In this paper we will discuss the detail MTF measurements of a 1024 × 1024 pixel multi-band quantum well infrared photodetector and 320 × 256 pixel long-wavelength InAs/GaSb superlattice infrared focal plane arrays.
► Demonstrated 18.6 mK NEDT with LWIR superlattice focal plane array. ► Demonstrated nine band multi-wavelength QWIP focal plane array. ► Measured the modulation transfer function of QWIP and Superlattice detector arrays.
