Projection apparatus for providing multiple viewing angle images

摘要

A projection apparatus is disclosed. The projection apparatus includes a light source module, a first light splitting element, a first light valve unit, a first light modulator, a second light modulator and a light consolidating element. A light beam is provided by the light source module, and is split into a first and a second polarized light beam by the first light splitting element. In different time sequences, the first and the second polarized light beams are formed into a first, a second, a third and a fourth image light by the first light valve unit. Then, these image lights are transformed into viewing angle images by the first and the second light modulators. Then, via the light consolidating element, the first, the second, the third and the fourth view angle images are projected to a viewer and a stereoscopic image is formed.

1. A projection apparatus for providing multiple viewing angle images, comprising:
a light source module for providing a light beam; a first light splitting element, dividing the light beam into a first polarized light beam and a second polarized light beam; a first light valve unit, wherein in a first time sequence, the first light valve unit transforms the first and the second polarized light beams into a first and a second image light respectively, and in a second time sequence, the first light valve unit transforms the first and the second polarized light beams into a third and a fourth image light respectively; a first light modulator for receiving the first image light in the first time sequence and for receiving the third image light in the second time sequence, wherein the first light modulator transforms the first and the third image lights into a first viewing angle image and a third viewing angle image respectively; a second light modulator for receiving the second image light in the first time sequence and for receiving the fourth image light in the second time sequence, wherein the second light modulator transforms the second and the fourth image lights into a second viewing angle image and a fourth viewing angle image respectively; and a light consolidating element for projecting the first and the second viewing angle images in the first time sequence, and for projecting the third and the fourth viewing angle images in the second time sequence.
