摘要

A mathematical model of an ideal observing thermal imager is developed. It was supposed at designing a model that: -the main noise source is a shot noise of photons irradiating photosensitive element (PSE); -temperatures and reflection factors of observed objects differ a little from corresponding scene characteristics; -image light brightness of i -th local object area on the indicator screen of the thermal imager (useful signal) is determined by the difference between on electric charge accumulated in PSE channel optically conjugated with this local area an electric charge accumulated in PSE channel optically conjugated with the scene.
