Abstract: A device to control the aiming and focusing of laser systems on a target comprises at least one reflecting false target (21) positioned and oriented substantially identically to the target (3), a lens (12) for the focusing of the beam on this false target, a separator device (11), a wavefront analyzer (35), a mirror (33) and a semi-reflective plate (32), the beam (1) getting focused, at the end of the system, on the false target (21) after getting reflected on the separator device (11). A part (31) of the beam with the same wavelength as that of the part reflected by the separator device (11) goes through this device and the semi-reflective plate (32) to get directed towards the wavefront analyzer (35). The beam reflected by the false target (21) goes through the separator grating (11) to get reflected on the mirror (33) and the semi-reflective plate (32) to get directed towards the wavefront analyzer (35).

Abstract: This monostatic LIDAR system is a pulsed-radiation LIDAR system comprising, for the separation of the laser emitter beam from the laser echo backscattered by the photodetector of the receiver, an optical separator that deflects an incident light beam in different directions, depending on whether it transmits or reflects this beam, the coefficient of transmission or the coefficient of reflection of this optical separator varying as a function of the energy density of said incident light beam. Advantageously, this optical separator is constituted by a layer of vanadium dioxide VO.sub.2 deposited on a transparent plate. An optical separator of this kind is used to obtain a total transmission/reception output greater than that of an optical separator with semi-reflective plate while, at the same time, preserving the advantages that an optical separator of this kind brings about in the optical architecture of a LIDAR, these advantages being simplicity, easy setting, compactness and low-level parasitic reflections.
