Abstract: A telecamera with a high frame frequency for detecting infrared radiation and visible radiation emitted by moving bodies has a lens, an optical device designed to subdivide the radiation into a flux of visible radiation and several fluxes of infrared radiation, several CCDs for detecting independently and sequentially the fluxes of infrared radiation, and one CCD for detecting the visible radiation. The data thus collected is converted into digital, optical and serial form and sent in a string to the central unit via an optical-fiber cable. The frame frequency which is obtained corresponds to the product obtained from the frequency of each CCD multiplied by the number of CCDs which detect the infrared radiation.
