Abstract: There is herein defined optics (e.g. an array of optics) forming an optical beam to either produce a collimated or diverging/converging beam emerging from a virtual source point to illuminate a hologram. There is also described an optical beam illuminating a reflection hologram from the front and a further configuration where an optical beam combined with a holographic optical element (HOE) minor enables rear illumination of a reflection hologram.
Abstract: There is herein described apparatus and methods for displaying holograms. At least one aspect of the invention is to provide a compact and self-contained lighting system for a display hologram, which can produce high quality images and which is substantially insensitive to stray light.
