Abstract:
1. A projector, comprising: a light source that emits an illumination flux; a first lens array having plural first small lenses that split the illumination flux from the light source into plural partial luminous fluxes; a second lens array having plural second small lenses corresponding to the plural first small lenses; a superimposing system including a superimposing lens and an optical lens, the superimposing system superimposing each of the partial luminous fluxes from the second lens array onto an illuminated area, the superimposing lens defining a focal length and a focal position; an electro-optic modulator that modulates the light superimposed by the superimposing lens in accordance with image information; and a projection system that projects the light modulated by the electro-optic modulator, the optical lens disposed in an optical path between the superimposing lens and the electro-optic modulator, a focal length of the superimposing system being different than the focal length of the superimposing lens, a focal position of the superimposing system being the same as the focal position of the superimposing lens.
