ABSTRACT:
A scanning radiometer in which at least one curved mirror is integral with a drivable optical system. Thermal radiation is directed onto a detector facing the mirror at a distance. An electronic system performs a weighting evaluation corresponding to the position of the detectors, and a threshold value is indicative of the degree of radiation of the observed object shown on a display unit. The optical system together with the detectors is located about axes containing the center of curvature of the curved mirror and is rotatable in steps or continuously. The mirror is, furthermore, shaped in the form of a hollow sphere or a hollow sphere segment. The latter avoids irradiation of detectors by scatter radiation incident via the aperture with boundaries running parallel to the optical axis or with a boundary expanding funnel-like from the entry window towards the mirror. The boundaries are the carrier body regions parallel to the optical axis, and these regions are covered on the inside with a highly absorbent lacquer corresponding to the wavelength range of the incident scatter radiation.
