摘要： A novel method for fabricating a micro-optics structure, having at least one lenslet array, is presented. A writing mask is provided being configured in accordance with an arrangement of the lenslet array to be manufactured. The writing mask is applied to a structure formed by a photosensitive layer of a predetermined thickness carried by a substrate, and the photosensitive layer is exposed through the writing mask using a predetermined spectral range of the exposure and a predetermined distance between the mask and said photosensitive layer, to thereby pattern the photosensitive layer through a diffractive optical element of said mask. The so-obtained pattern is in the form of optical nonhomogeneities in the photosensitive layer material, defining the lenslet array within the photosensitive layer.

摘要： A liquid crystal (LC) panel is presented. The LC panel is configured as an integrated multi-layer structure comprising an LC pixel matrix configured and operable for spatially modulating light passing therethrough, and at least one microlens array (MLA). The MLA is configured such that every pixel of the pixel matrix is associated with its corresponding microlens from said at least one MLA. The MLA has a curved surface defining an array of convex or concave surface regions of the microlens in the MLA, respectively, and an opposite planar surface which is common for all the microlenses in the MLA. The MLA by either one of its surface is spaced from an active surface of the pixel matrix or from another MLA by a spacer layer structure. The spacer layer structure has at least 10 microns thickness and at most 150 microns thickness, and is made either from an inorganic material by a sacrificial layer technology or from one or more organic polymer materials including an BCB layer.
