Abstract
The invention relates to a FMCW lidar imager system with improved distance resolution. The imager systemcomprises a reflectorconfigured to reflect, in the direction of the scene, a portion Sof the backscattered object signal S, which portion has not been collected by the collecting optical element. Thus, the collected portion Sof the backscattered object signal Sis formed from first light beams Sthat have not been reflected by the reflectorand from light beams Sthat have been reflected by the reflector. The heterodyne signal Stherefore has a principal component Sassociated with the light beams S, and a secondary component Sassociated with the light beams S. The processing unitis configured to determine the distance zof the sceneon the basis of a beat frequency fof the secondary component Sof the heterodyne signal S.
