Abstract
The invention concerns a device for emitting a light beam (10) intended to form an image, the device comprising one or more sources (4, 5, 6), each emitting a laser-type beam (7, 8, 9), the device being configured to form the light beam (10) from the one laser beam or from the combination of laser beams (7, 8, 9), the device comprising attenuation means (12) disposed downstream of the source(s) (3, 4, 5), enabling the optical power of the light beam (10) to be varied.
