Scanning ray video projection system and method, automotive head-up display using the system, and automotive adaptive lighting device

摘要

The present invention relates to a scanning ray video projection system. The system comprises a device (1) emitting a light beam (18) modulated by a video signal and scanning means (20) capable of polarizing said light beam (18) so that a video image (22) can be formed, and a light emitting device (1) includes at least two separate light sources (24, 25) respectively emitting sub-light rays (14, 15) of substantially different vertical polarization, and two sub-light rays (14) in the direction of the scanning means (20). , 15), comprising a recombination device (12) that forms said light beam (18) by adding together.
