IMAGE PROJECTION APPARATUS |
摘要 |
Provided is an image projection apparatus, such as a projector, including a light source; an image generating element such as a DMD that receives light from the light source and forms an image; an image generating unit that irradiates the image generating element with the light from the light source; a first optical system including multiple transmission refractive optical elements; a second optical system arranged on an optical path of outgoing light of the first optical system and including a reflection optical element; and a projection optical system that enlarges and projects an image conjugate to the image generated by the image generating element as a projected image. The light source, the image generating unit, and the first optical system are arranged side by side in series in a direction parallel with the projected image plane. |
