Abstract
A monitoring device for spatial areas comprises a receiver, to which an anamorphotic optical system, is assigned. The monitoring device also has a transmitter which scans a field of view assigned to the receiver using radiation pulse beams. A distance image of an object in the field of view can be produced by way of a radiation transit time determination with short-term integration carried out in an evaluation unit.
Claims15
A device for monitoring a space, comprising:
- a transmitter emitting light with temporal intensity changes;
- a receiver having one-dimensional resolution;
- an optical system, for assigning to said receiver a field of view, disposed in a radiation path in front of said receiver;
- said receiver receiving radiation pulses emitted by said transmitter into the field of view;
- an evaluation unit connected to said receiver and to said transmitter, said evaluation unit serving to determine a transit time of the radiation pulses;
- said transmitter subjecting the field of view to radiation pulse beams partially covering the field of view, and said evaluation unit receiving information concerning a shape of the radiation pulse beams in the field of view during determination of the transit time of the radiation pulse beams;
- and
- an anamorphotic optical system disposed to compress the field of view onto said receiver.
