Optical device and projection video display device
View Patent ↗The optical device includes a diffuser which diffuses light, a holder which holds the diffuser, a driver which vibrates the holder, and a supporter whose one end elastically supports the holder at one point and whose other end is fixed to an installation plane.
1. A projection video display device comprising:
a light source that emits coherent light;
a splitter that splits the light emitted from the light source into a first optical path and a second optical path; and
an optical device disposed on one of the first optical path and the second optical path, the optical device comprising:
a diffuser that diffuses light,
a holder that holds the diffuser,
a driver that vibrates the holder, and
a supporter whose one end elastically supports the holder at one point and whose other end is fixed to an installation plane.
2. A projection video display device comprising:
a light source that emits coherent light;
a splitter that splits the light emitted from the light source into a first optical path and a second optical path; and
an optical device disposed on both of the first optical path and the second optical path, the optical device comprising:
a diffuser that diffuses light,
a holder that holds the diffuser,
a driver that vibrates the holder, and
a supporter whose one end elastically supports the holder at one point and whose other end is fixed to an installation plane.
