Patent attributes
A multi-optical surface optical design for generating multiple focal planes with identical image data displayed at substantially the same time to generate the perception of varying focal depths is described. The multi-optical surface optical design can include a device comprising reflective optical surfaces that can be arranged on top of one another and configured to generate multiple focal planes and an image source for projecting image data onto the reflective optical surfaces. The technologies described can cause image data to be rendered in a focal plane corresponding to a desired focal distance and multiple copies of the image can be perceived in other focal planes of the multiple focal planes at substantially the same time as the image data is rendered in the focal plane. Each copy of the multiple copies can be presented with a perceived degree of sharpness such that each copy is out-of-focus.
