Summary: | The invention relates to a device for optically detecting an object or a person (P) in the passenger compartment of a vehicle. Said device contains a transmitter for transmitting an optical pulse train and a receiver (31) for receiving the optical pulses that are scattered on an object or a person (P) and for converting the received optical pulses into an electrical signal (Xin).
