Projector

摘要

A relay system (formed of a plurality of optical systems) that generates a spherical aberration allows each light ray flux to be so adjusted that the cross section thereof has a moderate size (moderate degree of spread) on an image panel surface of each color modulation light valve, that is, the light ray flux is not brought into complete focus but is blurred. Further, as the aberrations to be generated, the amount of spherical aberration is set to be much greater than those of the other third-order aberrations, whereby generated spots are allowed to have the same shape irrespective of the field position.

主权项

1. A projector comprising:
an illumination system, chat outputs light; a light modulator that modulates the light output ted from the illumination system; and a projection system that projects the light modulated by the light modulator, wherein the light modulator includes a first pixel matrix and a second pixel matrix arranged in series along an optical path of the light outputted from the illumination system and a relay system disposed on the optical path between the first pixel matrix and the second pixel matrix, and the relay system generates a greater amount of spherical aberration than the amounts of other third-order aberrations.
