Patent ID: 8643950

Claim:
An image augmenting window, comprising: at least one internally focused intermediate image lens, each of the at least one internally focused intermediate image lens having a respective first side and a respective rear side, the respective first side being opposite the respective rear side, each of the at least one internally focused intermediate image lens respectively comprising: a first lens portion receiving incoming light through the first side and focusing the incoming light into a focused image on an internal focal plane within the respective internally focused intermediate image lens, the first lens portion comprising Gradient Index (GRIN) refractive material extending continuously from the first side to the internal focal plane; and a projecting output optical structure refracting the focused image as a projected image exiting the rear side at an exit angle; at least one controllable light source, wherein each controllable light source within the at least one controllable light source comprises a respective light source lens emitting a respective afocal projection of a respective projected light, the respective light source lens being separate from each internally focused intermediate image lens within the at least one internally focused intermediate image lens, and the respective light source lens being positioned adjacent to a lateral side of a respective internally focused intermediate image lens within the at least one internally focused intermediate image lens, each respective controllable light source within the at least one controllable light source further emitting a respective projected light that is parallel to a respective exit angle of the at least one internally focused intermediate image lens; and a controller configured to independently control each of the at least one controllable light source.
