Abstract

The utmost parameters of ideal thermal imagers are analyzed at observation of conventionally point emitters, (emitters which angular sizes do not exceed a field of view angle of a separate photosensitive element of a thermal imager -PSE). The carrying out of such analysis has required: the account of a background radiation, an application of a mode model for calculation of radiative fields, in which the decomposition of radiation flows from a point source and background into spectral-spatial modes, an account of a lens diffraction and aberrations. The fundamental restrictions of responsivity and information capacity stipulated by a shot photon noise, irradiation PSE, were considered only. The mathematical models for calculations of a utmost sensitivity, dynamic range, thermal contrast and other utmost performances of an ideal thermal imager were designed.
