Abstract

The quality of thermal image is determined by the imager’s spatial resolution, a modulation transfer function of which depends on the lens’ aberrations and the detector’s matrix structure. It is proposed to determine the spatial resolution by using the geometric noise bandwidth GNBW, which is an analogue to video signal processing electronic system’s effective noise bandwidth. A relationship is established between the spatial resolution and the bandwidth GNBW. An example is presented for calculating the angular resolution of the imager having a diffraction-limited lens and a matrix detector.
