More Information
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). Electrical switching means are provided for filtering fractions (P1) in the electrical signal, whereby said fractions are produced by background light.
