摘要:
A waveguide hologram illumination system is based on thin substrate waveguides bearing a hologram on the surface through which light is diffracted out. A light source is optically coupled to the waveguide such that light emitted from the source is caused to propagate along the waveguide, being diffracted out at intersections with the surface of the waveguide on which the hologram is formed. The selective emission through the hologram can be advantageously used to illuminate display holograms or spatial light modulators. Provisions are made for rendering the amount of light emitted through the hologram uniform along the length of the hologram.
