Abstract
The invention relates to a LIDAR imaging system of the FMCW type, comprising a light source (), an optical projection device (), an optical transmission device (), an optical imaging device (), and a matrix photodetector (). It further comprises a phase correction device () comprising a spatial phase modulator () for applying a corrected spatial phase distribution to the reference signal, and a computation unit () for determining the corrected spatial phase distribution, by taking into account a spatial distribution representing a spatial intensity distribution of the backscattered object signal, so that the reference signal has a corrected spatial intensity distribution in the reception plane optimizing a spatial distribution of a parameter of interest representing the heterodyne signal.
