Abstract
A device for emitting a light beam intended to form an image including one or more sources, each emitting a beam of the laser type, and an attenuation means situated downstream of the source or sources that allows the varying of the optical power of the light beam by transmitting or reflecting the beam or beams as a function of a supply current of the attenuation means. The device forms the light beam from the one laser beam or from the bringing together of the laser beams by combination.
