  • Patent number: 11491908
    Abstract: The invention proposes a lighting device for a motor vehicle comprising a matrix light source that performs a lighting function within the motor vehicle. The same source is used, together with a photodiode, to estimate the time of flight of captured light pulses initially generated by the matrix source. It becomes possible to detect objects and/or gestures using light in the visible spectrum, and without having to use specific pulse sources dedicated for this purpose.
