Color Recapture using Polarization Recovery in a Color-Field Sequential Display System

摘要

An image may be formed in a projection system by forming a light beam with substantially a first polarization. The light beam is directed onto a first color wheel that transmits a first selected color portion of the light beam and reflects a second color portion of the light beam. The reflected second color portion is converted to a second polarization. A first portion of the image is produced with a first spatial light modulator using the first selected color portion of the light beam having the first polarization. A second portion of the image is produced with a second spatial light modulator using at least a portion of the reflected second color portion of the light beam having the second polarization. The first portion of the image and the second portion of the image are combined to form a combined image for projection.

主权项

1. A method for producing an image, the method comprising:
forming a light beam with substantially a first polarization; directing the light beam onto a first color wheel that transmits a first selected color portion of the light beam and reflects a second color portion of the light beam; converting the reflected second color portion to a second polarization; conducting the first selected color portion of the light beam having the first polarization through a first optical path to a first spatial light modulator and producing a first portion of the image with the first spatial light modulator; conducting a portion of the reflected second color portion having the second polarization through a second optical path to a second spatial light modulator and producing a second portion of the image with the second spatial light modulator, in which the second optical path is separate and distinct from the first optical path; and combining the first portion of the image and the second portion of the image to form a combined image for projection.
