Abstract
Abstract A reflective image plane module including light directing and reflecting structures and a wafer based active matrix mated thereto. A source of light is directed to the reflective image plane module wherein the wafer based active matrix imparts or encodes information onto a light beam reflected therefrom. The reflective image plane module projects the reflected beam for imaging or viewing, such as through one or more lens. The reflective image plane module includes a prism or mirror which passes the light or light component through a first surface to the wafer based active matrix mated to a second surface and which projects the reflected light from the first surface to be viewed or imaged. The wafer based active matrix includes a specular reflective back surface and an LC or similar type material formed thereon which is electronically altered to impart the information to the light beam reflected therefrom. The reflective image plane module can be utilized in various light encoding systems such as a monochrome projector including a single reflective image plane module or a full color system including three reflective image plane modules, one for each color, which then are combined on a screen or before projecting on the screem to form the full color projection image.
