Document Type and Number:
WIPO Patent Application WO/2024/068695
Kind Code:
A1
Abstract:
The invention relates to a system (1) for a motor vehicle, comprising an emitting module (2) having a light-emitting module (21) that includes a semiconductor light source (23) able to emit a light beam (F1), the spectrum of which has a peak (P1) at a given wavelength, and comprising a receiving module (3) able to receive a light beam (F2), wherein the receiving module comprises an elementary acquisition module (32) comprising a photodetector (32a), characterized in that the receiving module includes a bandpass optical filter (34) placed in front of the photodetector (32a), said optical filter comprising two semi-reflective plates (34a) and a device (34b) for adjusting the distance (d) separating the plates; and a control device (5) arranged to automatically control said distance to the value of a parameter for the light source influencing the given wavelength.
