ON-BOARD OBSERVATION SYSTEM COMPRISING A LIDAR FOR OBTAINING HIGH RESOLUTION THREE-DIMENSIONAL IMAGES

摘要

The general field of the invention is that of observation instruments intended to be carried on an aircraft or on a satellite comprising a telescope comprising a retro-reflecting system (21, 22) and a first imager (23) sensitive in a determined spectral band. The observation instrument according to the invention comprises: - a “lid lidar” type lidar comprising: - an emission laser (31) emitting pulses at a determined wavelength; - an emission optic (32); - the retro-reflecting system acting as an optical system for receiving echoes due to laser pulses; - a second imager (34); - A spectral separator (36) disposed in front of the focal plane of the retro-reflecting system, said separator transmitting the wavelength of the emission laser and reflecting the determined spectral band or vice versa. Image processing means (35) make it possible to process the images from the telescope and the lidar simultaneously.
