Claims9
A device for detecting an object or person in a passenger compartment of a vehicle, comprising:
- a laser to emit laser light pulses;
- an optical receiver or sensor to receive laser light pulses reflected off the object or the person;
- and
- a detection unit connected to the laser, which detects the receiving power continuously and switches off the laser light pulse when a limit value corresponding to an adequate receiving power is reached.
