Problems solved by technology

[0004] Although many advances have been made in increasing the usability, size, cost and performance of wearable display devices, there is still considerable room for improvement
In particular, the imaging optics that present the electronically processed image to the viewer are disappointing
Conventional design approaches have proven difficult to scale to the required size, weight, and placement requirements, and often struggle with issues related to field of view and distortion, eye distance, pupil size, and other factors

Embodiment Construction

[0033] The drawings shown and described herein are provided to illustrate key principles of operation and manufacture of optical devices according to various embodiments, many of which are not intended to show actual size or scale. Some exaggeration may be necessary to emphasize underlying structural relationships or principles of operation.

[0034] The drawings provided may not show the various support components, including optical mounts, power supplies, image data sources, and circuit board mounts that are standard features of the display device. Those skilled in the optics will appreciate that many types of standard mount and support assemblies may be used with embodiments of the present invention.

[0035] In the context of this disclosure, terms such as "top" and "bottom" or "above" and "below" or "beneath" are relative and are not used to denote any necessary orientation of components or surfaces, but are simply used Used to represent and distinguish views, opposing s...

Abstract

An optical apparatus for display to a viewer has a concave spherical mirror that has a center of curvature at the viewer's pupil and that has a second radius of curvature. An image generation apparatus forms an image onto a spherical diffusive surface, wherein the spherical diffusive surface has a first radius of curvature that is substantially half the length of the second radius of curvature. Abeam splitter is positioned along a principal axis of the concave spherical mirror and optically disposes the curved diffusive surface at the focal surface of the concave spherical mirror.

Description

[0001] This application claims the benefit of priority to U.S. Provisional Application Serial No. 62 / 238976, filed October 8, 2015, under 35 U.S.C. § 119, upon which this application is based and incorporated by reference in its entirety This article. technical field [0002] The present disclosure relates generally to wearable display devices and, more particularly, to apparatus and methods for wide-field-of-view head-mounted displays with a single-center pupil imaging system. Background technique [0003] Wearable display devices can provide image content to viewers in applications where using conventional display screens would be cumbersome. Head-mounted devices (HMDs) such as display goggles are being considered and used in various fields, with applications ranging from military, medical, dental, industrial and gaming fields, among others. Stereoscopic imaging, with its enhanced spatial representation and improved representation of relevant details, is particularly usef...
