Abstract
A full-color image capture system includes a color separation element and a single image sensor array. The color separation element can be operated in either a light reflective (mirror) mode in which selected intrinsic colors are reflected onto the image sensor array, or a light transmissive (filter) mode in which selected colors are transmitted to produce subtractive primary color images. The color separation element can be formed of holographic polymer dispersed liquid crystal materials that reflect light of selected intrinsic colors. The color separation element can include three holographic polymer dispersed liquid crystal material layers so that three different intrinsic colors can be selectively reflected or transmitted onto the image sensor to provide a full-color image.
