Optical system for a head mounted display combining high and low resolution images
First Claim
1. A display system comprisinga viewing location from which an image with a high resolution portion and a low resolution portion is viewed;
- a field of view in which the image is formed;
a high resolution image source for presenting the high resolution portion of the image at the field of view;
a low resolution image source for presenting the low resolution portion of the image at the field of view;
a reflective surface in the field of view;
one of the image sources forming its respective portion of the image on the reflective surface in the field of view whereby its reflection will be viewed at the viewed location;
the other of the image sources forming its respective portion of the image substantially in the same plane as the reflective surface, andwherein the high resolution image source forms its portion of the image in the same plane as the field of view and wherein the low resolution image source forms its portion of the real image on the reflective surface in the field of view.

Abstract
A display system includes a relatively higher resolution display for presenting visual information, and a relatively lower resolution display for presenting visual information, the displays being positioned to present the visual information images therefrom in substantially side-by-side relation, the lower resolution image being provided by the cooperation of focusing optics which form a real image at a retro-reflector, which reflects light along an optical path conjugate with light incident thereon to provide an image for viewing, and the higher resolution image being provided without passing through the focusing optics. A method of display includes forming a relatively lower resolution real image, reflecting the image to the eye of an observer, forming a relatively higher resolution image, and directing the relatively higher resolution image to the eye of the observer such that at least a portion of the relatively lower resolution image circumscribes at least a portion of the relatively higher resolution image.

17. A display system comprising a relatively higher resolution display for presenting a high resolution visual information image, a relatively lower resolution display for presenting a low resolution visual information image, a high resolution image source, a low resolution image source, focusing optics, a retroreflector, and a beamsplitter,
said displays being positioned to present the visual information images therefrom in substantially side-by-side relation, said focusing optics focusing light from said low resolution image source toward said retroreflector via said beamsplitter to form the low resolution visual information; -
said focusing optics being operative to form a real image from light received from said low resolution image source; said high resolution image source located in said retroreflector thereby to present the relatively higher resolution visual information image for viewing while being surrounded by the real image.

22. A display system comprising:
-
a viewing location; a first display, including a retroreflector, means for focusing an image toward said retroreflector, and a pair of beamsplitter means for reflecting and transmitting light relative to said retroreflector, whereby one of said beamsplitter means transmits light and reflects light toward said retroreflector for focusing at said retroreflector and the other of said beamsplitter means transmits light and reflects light from said retroreflector for viewing at the viewing location, and a second display including means for presenting a relatively higher resolution image than the image presented by said first display, and means for presenting the relatively higher resolution image within the image presented by said first display; wherein said means for presenting of said second display is positioned at least substantially at said retroreflector. - View Dependent Claims (23)
