MULTI-DEPTH AUGMENTED REALITY DISPLAY
First Claim
1. An imaging system for generating multi-depth virtual images on a display screen, the imaging system comprising:
- an image realisation device for forming a source image; and
projection optics for rendering a display image on the display screen, wherein the display image is a virtual image corresponding to the source image, andwherein the image realisation device comprises;
an image realisation surface having a first and second region, wherein the image realisation surface and the projection optics are arranged such that a first point in the first region of the image realisation surface and a second point in the second region of the image realisation surface are at a different distance from a focal point of the projection optics; and
a plurality of surfaces arranged to direct light from the image realisation surface towards the projection optics,wherein the surfaces and image realisation surface are arranged such that a first source image formed on the first region of the image realisation surface and projected through the projection optics will render the first display image on the display screen at a first apparent depth and a second source image formed on the second region of the image realisation surface and projected through the projection optics will render the second display image on the display screen at a second apparent depth; and
wherein two or more of the plurality of surfaces are beam splitters having reflection/transmission ratios, wherein each beam splitter has a different reflection/transmission ratio, and wherein the reflection/transmission ratios are such that the brightness of the first and second display image is approximately equal.

Abstract
An imaging system for generating multi-depth virtual images on a display screen includes an image realisation device for forming a source image, and projection optics for rendering a display image on the display screen. The display image is a virtual image corresponding to the source image. The image realisation device includes an image realisation surface having a first and second region, and the image receiving surface and the projection optics are arranged such that a first point in the first region of the image receiving surface and a second point in the second region of the image receiving surface are at a different distance from a focal point of the projection optics. A plurality of surfaces are arranged to direct light from the image realisation surface towards the projection optics.
