Document Type and Number:
Japanese Patent JP2018189969
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a device for emitting a light beam intended to form an image.SOLUTION: A device for emitting a light beam 10 intended to form an image. The device comprises one or more sources 4, 5, and 6, each emitting laser-type beams 7, 8, and 9. The device is configured to form the light beam 10 by the one laser beam or by combining and collecting the laser beams 7, 8, and 9. The device comprises attenuation means 12, disposed downstream of at least the one or more source(s) 4, 5, and 6, enabling optical power of the light beam 10 to be varied. The attenuation means comprises one or more retractable filters 20 which can be interposed in one or more of the laser beams.SELECTED DRAWING: Figure 1
