摘要： The optoelectronic rotary scanning device comprises optical receiving means, optical elements driven together in rotation by an afocal system consisting of at least two cylindrical optical elements designed to rotate about an axis perpendicular to the plane of their generator-lines, and an optical element for focusing on an array of detectors extending radially from the perpendicular axis. Videofrequency means are provided for processing the signals delivered by the detectors, the signals being multiplexed and stored sequentially in memory after transcription to cartesian coordinates. The videofrequency processing means also comprise a loop which subtracts the integrated mean value of the signals of all the detectors from each signal of each detector and a circuit for correcting thermal-drift residual voltages of the amplifying circuits of the detectors.
