ONBOARD OBSERVATION SYSTEM COMPRISING A LIDAR FOR HIGH RESOLUTION THREE DIMENSIONAL IMAGES

摘要

The general field of the invention is that of observation instruments intended to be on board an aircraft or satellite comprising a telescope comprising a catadioptric system (21, 22) and a first imager (23) sensitive in a specific spectral band. The observation instrument according to the invention comprises: a lidar of the "flash lidar" type comprising: a transmission laser (31) emitting pulses at a determined wavelength; an emission optics (32); - the catadioptric system acting as optical reception echoes due to laser pulses; a second imager (34); a spectral separator (36) arranged in front of the focal plane of the catadioptric 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.
