摘要： A light modulation element comprising an optical member is provided. The optical member comprises: a light control part to reflect light in a predetermined wavelength and to transmit light in other than the predetermined wavelength in light in at least a visible light range in accordance with a reproduction reference image for reproducing an original image; and a light transmissive part to transmit light in at least the visible light range including the predetermined wavelength, wherein the optical member comprises a hologram recording layer, and the light control part is an interference fringe in the hologram recording layer, and wherein the optical member makes an observer visually perceive a reproduced optical image of a color of the predetermined wavelength when a point light source is observed through a predetermined region including the interference fringe in the hologram recording layer from a normal direction to the optical member in a state where light in a predetermined wavelength range including the predetermined wavelength is incident from the point light source on the predetermined region, and makes an observer visually perceive a reproduced optical image of a color of a shorter wavelength than the predetermined wavelength when the point light source is observed through the predetermined region from a direction oblique to the normal direction.

摘要： A method of manufacturing a light control film. The method comprises providing a plurality of alternating layers of transparent material and light absorbing material. Each layer of light absorbing material is interspersed between respective layers of transparent material. The plurality of alternating layers of transparent material and light absorbing material is stacked in a stacking direction. The stacking direction is perpendicular to the plane of a surface of at least one of the plurality of alternating layers. The method further comprises cutting, with a straight edge, through the plurality of alternating layers of transparent material and light absorbing material in a first cutting plane and a second cutting plane thereby resulting in an intermediate film comprising a first cut surface parallel to the first cutting plane and a second cut surface parallel to the second cutting plane. Each of the first and second cutting planes is orientated at an angle less than or equal to 90° to the stacking direction. The method further comprises hot embossing, using a tool having a repeating prismatic structure, the repeating prismatic structure on the first cut surface of the intermediate film thereby resulting in a serrated/corrugated first surface.

摘要： A holographic cloaking or concealment system and method having a meshed structure formed by one or more holographic optical elements configurable according to at least one of the following parameters: (a) the wavelength (λ) or color to be diffracted; (b) the bandwidth (Δλ) or amount of that color to be diffracted; (c) the diffraction efficiency (η) or percentage to be diffracted with respect to the incident light; and (d) the diffraction direction (α); in such a way that said holographic optical elements form one or more diffractive reflection blocks, whose optical properties are selected according to the optical effect required by a predetermined camouflage or concealment pattern in the visible spectrum and/or in the near infrared and/or in the ultraviolet.
