PROBLEM TO BE SOLVED: To provide a projector that forms projection image light by coherent laser beams, capable of meeting a conventional requirement of more securely removing speckle noise, the speckle noise remaining in a projection image based on laser beams even if the speckle noise in the projection image is reduced and removed.SOLUTION: A light source device includes: a light source 71 for emitting a laser beam; a plurality of diffuser panels into which the laser beam is incident and from which the incident laser beam is emitted as diffusion light; and a drive mechanism for moving the plurality of diffuser panels. The laser beam from the light source is incident on one diffuser panel from among the plurality of diffuser panels. The diffusion light emitted from the one diffuser panel is incident on another diffuser panel from among the plurality of diffuser panels. |
