Abstract
The invention relates to a scanned light beam video projection system. The system is characterised in that it comprises a device (1) for emitting a light beam (18) modulated by a video signal, and scanning means (20) able to deviate said light beam (18) in order to allow a video image (22) to be formed, the emitting device (1) comprising at least two separate light sources (24, 25) each emitting a light sub-beans (14, 15) of different substantially rectilinear polarisation to the other, and a recombining device (12) configured to form said light beam (18) by adding the two light sub-brams (14, 15), in the direction of the scanning means (20).
