Abstract: A micro-optical device for double-sided imaging, a preparation method therefor and an application thereof. The micro-optical device for double-sided imaging comprises a first microlens layer (1), a functional layer (4), a second microlens layer (2) and a miniature graphic layer (3) which are mutually compounded in sequence, the first microlens layer (1) being a first microlens array formed by arranging a plurality of first microlenses (11), and the second microlens layer (2) being a second microlens array formed by arranging a plurality of second microlenses (21); and the functional layer (4) is arranged on the surface of the second microlens layer (2), and a material for the functional layer (4) has a refractive index different from that of a surrounding material.

Abstract: A sensitive liquid crystalline polymeric material suitable for the reflective hologram recording and the preparing method thereof are disclosed. The material includes a base film, a buffer layer coated on one side of the base film, a sensitive polymeric layer coated on the other side of the buffer layer and a protective layer coated on the surface of the sensitive polymeric layer.

Abstract: A photosensitive film for holographic recording and its production method thereof are disclosed. The film comprises a base film, a buffer layer coated on one side of the base film, a photosensitive polymer coating layer formed by applying a photosensitive coating on the other side of the buffer layer, and a surface protective film covering the surface of the photosensitive polymer coating layer. Interference fringe patterns of a holographic image or an amphichronic graph are recorded in the photosensitive polymer coating layer. The film according to the present invention is a photosensitive material composed of two polymers of different refractive indexes, when coherent light beams intersect in its recording medium and produce an interference fringe pattern in the medium, monomers therein are excited accordingly and undergo free radical polymerization, thereby forming a hologram.
