Document Type and Number:
Japanese Patent JP4556112
Kind Code:
B2
Abstract:
In a light scanning apparatus including an optical system including a beam deflection means therein and a one-dimensional light modulation device, the one-dimensional light modulation device is disposed on the object side of the optical system, and the beam deflection means is disposed at a diaphragm position. In the optical system, a positive-power former group and a positive-power latter group are arranged, and a one-dimensional image obtained through light modulation by the one-dimensional light modulation device is scanned by the beam deflection means, to thereby form a two-dimensional image on an image plane of the optical system. In application to a projector apparatus or the like, the two-dimensional image can be enlargedly projected by a projecting optical system.
