  • Patent number: 7628940
    Abstract: Disclosed is a method for manufacturing an optical component in three dimensions. In one aspect, the method includes providing a substrate that includes contiguous rigid plates that are disposed such that a major surface of each rigid plate lies substantially in a single plane. At least one of said surfaces is characterized by a micro-optical structure. Further in the method, the substrate is folded such that the at least one surface having a micro-optical structure and at least one other of the above-recited surfaces are disposed at an angle to one another. A second method is also disclosed. Disclosed structures made by the method(s) include a mesa structure with a top plate and four sidewall plates, each facing a reflective plate, as well as closed structures such as cubes and rectilinear boxes into which separate plates may be disposed. A mold for preferentially making the substrate such as by injection molding is also detailed.

  • Patent number: 7270428
    Abstract: The present solution relates to a 2D/3D data projector, which comprises: A data projector, the data projector comprising: at least one micro display having an image to be projected, at least one source unit comprising at least one light source chip and at least one beam forming component, each beam forming component comprising at least one diffractive element, and each source unit being designed to preserve etendue as far as possible, to minimize photon loss, to provide a desired projection shape and a uniform illumination onto the micro display, and a focusing optical unit for projecting the image of the micro display on a target.
