Embodiment Construction

[0020]FIG. 2 is a schematic view of an optical projection and image sensing apparatus according to an embodiment of the present invention. Referring to FIG. 2, the optical projection and image sensing apparatus 200 of the present embodiment comprises a light source 210, a light valve 220, a first lens set 230, a sensing module 240, and a beam splitter 250. The light source 210 is used to provide an illumination light 212. The light valve 220 is disposed on the optical path of the illumination light 212, so as to convert the illumination light 212 to an image light 213. The first lens set 230 is disposed on the optical path of the image light 213 for projecting the image light 213 to display an image on a screen 50. The sensing module 240 is used to sense a sensing light from the image on the screen 50. The beam splitter 250 is disposed on the optical path of the image light 213 and the optical path of the sensing light 52. The beam splitter 250 is used to reflect a part of the sensi...

Abstract

An optical projection and image sensing apparatus including a light source, a light valve, a first lens set, a sensing module, and a beam splitter is provided. The light valve is used to convert an illumination light from the light source to an image light beam. The first lens set is used to project the image light to display an image on a screen, and the sensing module is used to sense a sensing light from the image on the screen. The beam splitter is disposed on the optical paths of the image light and the sensing light from the image on the screen. One of the sensing module and the light valve is disposed on the optical path of the sensing light passing through the beam splitter, and the other is disposed on optical path of the sensing light reflected by the beam splitter.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the priority benefit of Taiwan application serial no. 95116328, filed May 9, 2006. All disclosure of the Taiwan application is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of Invention[0003]The present invention relates to an image display apparatus.
