Abstract: An apparatus for recording a holographic device comprises: a master hologram comprising a multiplicity of holographic elements each characterized by one of a predefined set of grating prescriptions; a transparent substrate supporting a layer of holographic material; and a light source. Each holographic element diffracts source light onto a predefined region of the layer. Each prescription modulates at least one of phase, amplitude, and angle of the light. There is further provided a method of recording a holographic device, comprising the steps of: providing said apparatus; exposing the master to illumination from the source; and diffracting light from each holographic element onto a predefined region of the layer.

Abstract: An internal device having a lightguide which cooperates with an internal light source. A first light coupling element couples an external light source to the lightguide and a second light coupling element extracts the total internal reflection (TIR) from the lightguide. Between the first and second lightguides, an angular grating device and phase grating device are imposed. The angular grating device applies angular diversity to the rays of the TIR light, while the phase grating device applies phase diversity to the rays of the TIR light. Each of the grating devices has a plurality of electrically switchable grating pixels having a unique first and second diffracting state which varies based on the applied voltage.
