Abstract:
There is provided a light source unit having a light source which emits a laser beam, a plurality of diffusing plates on which the laser beam is incident and which emit the laser beam incident thereon as diffuse light, and a driving mechanism which moves the plurality of diffusing plates, wherein the laser beam from the light source is incident on one diffusing plate of the plurality of diffusing plates, and diffuse light emitted from the one diffusing plate is incident on the other diffusing plate of the plurality of diffusing plates.
