Abstract
A lidar, which includes a transmitter and a receiver, as well as an optical system, which is arranged to direct at least part of the light sent by the transmitter as a transmitter beam progressing towards an object and to define the receiver beam to the receiver, at least part of the light arriving from the zone of which is focussed on the receiver. The optical system of the lidar is implemented in such a way that the beams immediately in front of the lidar are located essentially outside of each and one of the beams at least partially surrounds the other beam. The optical system includes an integrated optical, which has a first area for forming the transmitter beam, and a second area for forming the receiver beam.
