Title:
DETECTING AND/OR COMMUNICATING SYSTEM FOR A MOTOR VEHICLE COMPRISING A MODULE FOR EMITTING AND A MODULE FOR RECEIVING A LIGHT BEAM
Document Type and Number:
WIPO Patent Application WO/2024/068697
Kind Code:
A1
Abstract:
The invention relates to a system (1) comprising an emitting module (2) comprising a light-emitting module (21) able to emit a light beam (F1) the spectrum of which has at least one portion in the visible spectrum and a linear polarizer device (25) arranged to polarize said emitted light beam in a given polarization direction (P), and a receiving module (3) able to receive a light beam (F2), in which the receiving module comprises an elementary acquiring module (32) comprising a photodetector (32a) able to convert a light signal that it receives into an electrical signal, characterized in that the receiving module comprises a linear polarizer filter (34) arranged to transmit to the elementary acquiring module only the component of said received light beam polarized in said given polarization direction.
