摘要： A holographic display system comprises a light source configured to emit at least partially coherent light; a modulator arranged to be illuminated by the at least partially coherent light and to generate a light field which is a quantised representation of a target light field, H; and a spatial filter delimiting an aperture in a Fourier plane. A Fourier transform of the target light field, F(H), substantially does not overlap (i) a Fourier transform of a complex conjugate of the target light field, F(H*), (ii) a Fourier transform of the target light field multiplied by the complex conjugate of the target light field, F(HH*), (iii) a Fourier transform of a square of the target light field, F(H2), and (iv) a Fourier transform of a square of the complex conjugate of the light field F(H*2). The aperture substantially corresponds to F(H) in the Fourier plane.

摘要： A method for producing a computer-generated hologram including producing a reference beam, producing an object beam, applying computer-generated information regarding the hologram to the object beam, overlapping the object beam and the reference beam on or in a light-sensitive recording medium in order to apply the hologram by exposure, wherein several portions of the light-sensitive recording medium are exposed, one after the other, to the object beam and the reference beam simultaneously in order to produce a plurality of sub-holograms, wherein the angle of incidence at which the reference beam hits the surface of a first portion of the recording medium is different from the angle of incidence at which the reference beam hits the surface of a second portion of the recording medium. A change in the angle of incidence of the reference beam is achieved by changing the point of incidence of the reference beam on a lens.

摘要： Techniques disclosed herein relate to holographic optical materials and elements. An example of a holographic recording material includes matrix monomers characterized by a first refractive index and configured to polymerize to form a polymer matrix, writing monomers dispersed in the matrix monomers and characterized by a second refractive index different from the first refractive index, and a photocatalyst for controlled radical polymerization of the writing monomers. The writing monomers are configured to polymerize upon exposed to recording light. The photocatalyst is dispersed in the matrix monomers. The photocatalyst includes, for example, a transition metal photocatalyst or a metal-free organic photocatalyst, such as a photocatalyst for atom transfer radical polymerization or a transition metal photocatalyst for addition fragmentation chain transfer polymerization.
