Abstract

Colored illumination control systems implemented with illumination amplifiers, such as liquid crystal devices, are provided. Heat transfer devices remove heat, such as heat caused by the high intensity illumination, from the illumination amplifier. The colored illumination amplifiers can be implemented in either transmissive or reflective modes. In a reflective mode, illumination can be reflected from a front side and heat can be removed from a back side of the illumination amplifier. Color is provided, such as generating multiple channels of different color images and projecting the different color images to generate a multicolored image.
