Abstract
Provided is a projector capable of suppressing deterioration of a portion of a projection portion irradiated with a laser beam while improving brightness. This projector is formed to deviate optical axes of laser beams emitted from a plurality of laser beam generation portions respectively from each other so that the laser beams emitted from the plurality of laser beam generation portions respectively do not concentrate on one point of a projection portion.
Claims20
A projector comprising:
- a plurality of laser beam generation portions emitting laser beams having substantially identical lasing wavelengths;
- and
- a projection portion projecting an image onto an arbitrary projection area by scanning the laser beams emitted from the plurality of laser beam generation portions respectively, and
- formed to deviate optical axes of the laser beams emitted from the plurality of laser beam generation portions respectively from each other so that the laser beams emitted from the plurality of laser beam generation portions respectively do not concentrate on one point of the projection portion.
