Embodiment Construction
[0058] The following description is directed in particular to elements which form part of, or directly cooperate with, the apparatus of the invention. It will be apparent that elements not particularly shown or described may take various forms well known to those skilled in the art.
[0059] refer to figure 1 , a perspective view of the autostereoscopic imaging system 10 is shown in the figure. Viewer 12 is seated to view virtual stereoscopic images from left and right viewing pupils 141 and 14r. When the left and right eye pupils 681 ( figure 1 Optimum viewing conditions are obtained when the positions of 68r and 68r coincide with the positions of the corresponding left and right viewing pupils 14l and 14r.
[0060] Left image generation system 701 and right image generation system 7Or work together to provide virtual image 106 for stereoscopic viewing. The left and right image generation systems 701 and 70r work in a similar manner and interact with the other elements of...

The essentially monocentric configuration of the optical elements provides a stereoscopic display of the virtual image electronically scanned by means of a flexible optical waveguide through resonant excitation of a resonant fiber optic scanner (137) and realized by means of a spherical lens assembly (30) in the form of an intermediate image. The form is projected onto the vicinity of the focal plane (22) of the curved mirror (24). To form the respective left and right intermediate image components, the separate left and right image generation systems (70) each include a resonant fiber optic scanner (137), which itself includes a resonant cantilever section (139) of an optical fiber (138), which will The modulated light beam is directed to the curved surface (40) for projection by the spherical lens assembly (30). The single center configuration of the optical elements images the left and right scanning spherical lens pupils onto the respective left and right viewing pupils (14) of the viewer (12) and provides a single center of curvature for the projection elements. Using this monocentric configuration with a curved intermediate image source and spherical lens assembly (30) provides an exceptionally wide field of view with a large observation pupil (14).
Description
technical field [0001] The present invention relates generally to autostereoscopic display systems for viewing electronically generated images, and more particularly to apparatus and methods for generating left-eye and right-eye images using resonant fiber optic elements to form images, so The device has a monocentric configuration of optical elements to provide a very wide field of view and a large exit pupil. Background technique [0002] The potential value of autostereoscopic display systems is well known, especially in the fields of entertainment and simulation. Autostereoscopic display systems include "immersion" systems for providing a viewer with a realistic viewing experience by visually surrounding the viewer with a 3-dimensional image with a very wide field of view. Unlike most stereoscopic displays, an autostereoscopic display feature does not require any type of wearable item, such as goggles, headgear or special glasses. That is, autostereoscopic displays att...
