摘要:
A substantially monocentric arrangement of optical components provides stereoscopic display of a real image, electronically scanned by resonant actuation of a resonant fiber scanner (137) using a flexible optical waveguide and projected toward a curved retro-reflective surface (124). To form each left and right intermediate image component, separate left and right image generation systems (70) each comprise a resonant fiber scanner (137) that itself comprises a resonant cantilever portion (139) of optical fiber (138) that directs a modulated beam in a curved pattern for projection, such as by a ball lens assembly (30). A monocentric arrangement of optical components images the left and right ball lens pupil at the corresponding left and right viewing pupil (14) of the observer (12) and essentially provides a single center of curvature for projection components. Use of such a monocentric arrangement provides an exceptionally wide field of view with large viewing pupils (14).
