Abstract

A holographic display system having a dynamic image source including selectively activated light emitting diodes for providing spectrally narrowband and narrow beam imaging illumination through an apertured mask, and further having a mirror reflection hologram for reflecting the image to provide an observable virtual image. The image source further includes a polarizer and an optional diffuser.
