ABSTRACT:
An image display system is designed to provide a magnified presentation of the object for direct visual viewing with emphasis on low distortion and high apparent brightness. The image display system comprises two optical components: a concave Fresnel mirror surface and a second planar mirror surface, each coated with highly reflective material. Because there are two reflections in the optical path between the eye and the object, the presentation will be erect and right reading. The use of metallic coating will assure a high gain transfer of optical radiation from the object to the eye.
