    摘要: A holographic 3D recording device includes: a photorefractive crystal and a microlens array. The microlens array includes an array face and a side face. The microlens array is provided in a light path from an object to be photographed to the photorefractive crystal such that first light of object emitted through a diffuse reflection of the object to be photographed passes through the array face of the microlens array and becomes second light of object that is emitted to the photorefractive crystal. The photorefractive crystal is configured to receive the second light of object emitted by the microlens array and reference light, respectively, and save therein an interference fringe formed by the reference light and the second light of object. The first light of object and the reference light are coherent light.

    摘要: A system and method may utilize holography to facilitate fabrication techniques such as 3D printing and lithography. The system may include a light source, a hologram of an original object or lithographic pattern recorded in a holographic medium, and a target such as a reservoir of photosensitive material or a photosensitive material attached to a substrate. Illuminating the hologram with the appropriate light source may cause a holographic image of the original object or lithographic pattern to form on the photosensitive material within the reservoir or on the substrate. Formation of the holographic image may result in the formation of a new object from the photosensitive material, or may facilitate removal or retention of photosensitive material as part of a lithographic process.

    摘要: A full-parallax acousto-optic/electro-optic holographic video display includes a control layer and a piezo-electric layer, which includes a substrate and an array of anisotropic waveguide elements. Each waveguide element guides light into a single polarization and includes a horizontal grating, which diffracts light horizontally and comprises surface acoustic waves, and vertical grating, which diffracts light vertically and includes an electro-optic phased array. The surface acoustic waves propagate linearly with the guided, polarized light in the waveguide, converting the polarized light into a leaky mode of orthogonal polarized light. The combination of the horizontal and vertical gratings allows the waveguide element to focus light to multiple points and steer it in order to form a holographic image. The horizontal grating may be generated by interdigital acousto-optic transducers and the vertical grating may be controlled by electro-optic transducers. Each waveguide element may be subdivided into sub-waveguides that form the electro-optic phased array.

    摘要: The present disclosure relates to a thin flat type convergence lens. The present disclosure suggests a thin flat type convergence lens including: a transparent substrate; and a film lens including a transparent film attached on one side of the transparent substrate and an interference fringe pattern written on the transparent film. The convergence lens according to the present disclosure has a merit of thin thickness and light weight even if it has large diagonal area, so it is easy to develop thin flat type large area holography 3D display system.
