3D optical projection device
First Claim
1. An optical projection device, comprising:
- an imaging device comprising a first image portion and a second image portion, the first and second image portions being adapted to generate a first and a second image in a first and a second light beam, respectively;
a first converting device that is adapted to convert a polarization state of one of the first and the second light beams into a converted polarization state, so that the first and the second light beams are in different polarization states;
a relay lens comprising a combining device, that is configured to combine the first and the second light beams to form a superimposed image, and imaging optics configured to generate an intermediate image from the superimposed image, anda projection lens that is adapted to project the intermediate image onto a screen.

Abstract
An optical projection device comprises an imaging device adapted to generate a first and a second image in a first and a second light beam, respectively, a first converting device that is adapted to convert a polarization state of one of the first and the second light beams into a converted polarization state, so that the first and the second light beams are in different polarization states, and a relay lens that is adapted to generate an intermediate image, by superimposing the first and the second images. The relay lens comprises a combining device, that is adapted to combine the first and the second light beams. The optical projection device further comprises a projection lens that is adapted to project the intermediate image onto a screen.

10. An optical projection device, comprising:
-
an imaging device adapted to generate in a 3D mode a first and a second image in a first and a second light beam, respectively, the first and the second light beam being in the same polarization state, the imaging device further being adapted to generate in a 2D mode a single image in a single light beam; a first relay lens operating in the 3D mode, comprising a first converting device that is adapted to convert the polarization state of one of the first and the second light beams into a converted polarization state, the first relay lens being adapted to generate an intermediate image by superimposing the first and the second images being in different polarization states; a second relay lens operating in the 2D mode that is adapted to generate an intermediate image of the single image, the first and the second relay lenses being mounted in the optical projection device in such a manner, so that they can be alternatively placed in a light path comprising the first and second light beams in the 3D mode or the single light beam in the 2D mode; and a projection lens that is adapted to project the intermediate image onto a screen. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
