Abstract

Laser active imaging system allowing in particular to use a wide field by means of a detecting device including a linear array of N juxtaposed photodetector elements oriented along the direction of scanning and associated with a focusing lens. The receiver includes a circuitry receiving the N detected channels and is equipped with compensation circuits for the time shift exhibited by the video signals as a function of the distance so as to bring the illuminated objects back to their angular location for the display of the observed field. The processing circuits include circuits for measuring the amplitude and the Doppler shift and for identification of the distance through the rank of the detection channel.
