Abstract

A scanned light display system (100) includes a light source (102) operable to emit light and a curved mirror (108) positioned to receive at least a portion of the light. The curved mirror (108) is configured to substantially collimate the received light. The substantially collimated light is scanned to form an image by moving at least one of the light source (102) and the curved mirror (108) relative to each other. Alternatively, the scanned light display system (100) includes a light source (102) operable to emit light, a curved mirror (108) positioned to receive some of the light, and an optical element (124) positioned to receive light reflected from the curved mirror (108). The optical element (124) is configured to substantially collimate the reflected light. The substantially collimated light is scanned to form an image by moving at least one of the light source (102), the curved mirror (108), and the optical element (124). Scanning mirror assemblies and methods of making are also disclosed.
