    摘要： The invention relates to light emitting devices (2) with variable output color. More specifically, the inventions provides a color conversion cell (10) which can be positioned in front of a light source (4) in order to generate other color or color temperatures. Typically the light source is a light emitting diode (LED) which is power efficient but emits in a narrow and fixed spectra. The new colors are generated by photoluminescence in fluorescent dyes contained in the cell. The color converting of the cell is electrically controllable, preferably by controlling the orientation, density or distribution of the fluorescent dyes, or by controlling a pathlength of the light in the cell.

    摘要： A dynamic hologram is formed in anisotropic liquid crystal (LC) gel materials. By applying an electric field, the orientation of part of the liquid crystals can be altered and the hologram can be turned on and off. Using LC gels allows for holographic elements with no diffraction in the voltage off state so that the hologram appears only during application of an electric field. Also, the anisotropic LC gels maintain polarization dependence. The dynamic holograms are suitable in e.g. dynamic holographic optical components whereby an optical function can be included/excluded in a beam path without introducing or removing elements.

    摘要： The present invention provides a polarization independent phase modulator for light comprising a layer of chiral liquid crystal mixture that has a low enough pitch to provide polarization independence of the effective refractive index for visible light. The liquid crystal mixture is controllable between a helix oriented ground state and a tilted state induced by the application of an electric field across the liquid crystal mixture layer. The liquid crystal mixture is preferably dispersed in a network material which ensures that the helix-oriented ground state is resumed when removing the electric field.

Further a method of forming a recording structure in such an optical recording medium is proposed. Further, systems for recording and reproducing information stored on such an optical memory device are proposed. In the system for reproducing information an incident light beam induces increased conductivity in said photo inducible conductor layer and light emitted from said electroluminescent layer in response to said incident light beam is directed onto a detector. In the system for recording information an incident light beam suitable for degrading said photo inducible conductor layer material and/or said electroluminescent layer material is generated.
