Lens-based image augmenting optical window with intermediate real image
Abstract:
An image augmenting window and method of operation. An image augmenting window has at least one selectably transmissive internally focused intermediate image lens with a first portion that receives light and focuses it into a focused image on an internal focal plane. An output optical structure refracts the focused image out as a projected image. A selectably transmissive shutter located in the internal focal plane selectably blocks at least a portion of light passing through the lens. At least one controllable light source has a respective light source lens that is separate from and positioned adjacent to a lateral side of a respective selectably transmissive internally focused intermediate image lens and that emits an afocal projection of respective projected light. A controller independently controls each shutter and each controllable light source.
