    摘要: A monolithic element has a substrate body and at least one macro-optical characteristic integral in a first portion of the optical element. A plurality of surface micro-structures are integral in a portion of the optical element. The micro-structures are designed to homogenize light passing through the optical element to produce a predetermined pattern of smoothly varying, non-discontinuous light exiting the optical element. The light exiting the optical element is therefore altered according to both the macro-optical characteristic of the optical element as well as the homogenizing characteristics of the micro-structures.

    摘要: A vehicle light assembly includes a lens cover from which light emanates. A light shaping surface microstructure is carried in a portion of the light assembly. The microstructure can be incorporated into many different surfaces of the light assembly such as a surface of the lens cover, a surface of a macro-optical structure on the lens cover, or on a reflective surface of the assembly. The microstructure homogenizes and directs light emanating from the light assembly via reflection or transmission to provide a smooth, continuous pattern of light having a predetermined distribution shape or envelope and a predetermined directionality.

    摘要: A viewing surface in the form of a passive liquid crystal display or front projection viewing screen includes a substrate layer of material having a front side and a back side. A light shaping micro-sculpted surface structure is provided on one side of the substrate layer wherein the microstructure controls the directionality, gain, homogeneity and shape distribution of the light propagated by the screen or display. A reflective layer is deposited on the opposite back side of the substrate layer and reflects light incident upon the substrate layer back through the substrate layer toward a viewing screen surface. This type of construction can be used directly as a viewing screen or can be utilized behind a display such as a liquid crystal display in order to significantly enhance the brightness of such a display or screen. The microstructure can be integral on either the front side of the substrate layer or beneath the reflective layer on the back side of the layer.

    摘要: An apparatus for projecting light on to a predetermined area includes a light source and a transparent element disposed adjacent the light source where in the transparent element is made from a sol-gel type glass, quartz, or other optical material. A plurality of surface micro-structures integral in a surface of the transparent element are provided which both homogenize and control directionality of light passing form the light source through the transparent element. These micro-structures produce a predetermined pattern of highly transmissive, smoothly varying, non-discontinuous light in a predetermined direction which is suitable for any number of applications wherein a sol-gel material transparent element including the diffuser surface structures are particularly well suited.

    摘要: An authentication system using a correlator that correlates an input with a reference wherein at least one of the input and reference comprises a phase volume mask having structures, preferably points, that are each less than about six microns in size and can have an aspect ratio (AR) greater than 1:1 so as to produce a phase encoded random pattern having millions of combinations in a mask that is as small as one square millimeter. The random pattern can be convolved with a second pattern, such as a biometric pattern, to produce a phase convolved mask. The correlator preferably is a nonlinear joint transform correlator that can use “chirp” encoding to permit the input to be located in a different plane than the reference. The correlator optically Fourier transforms images of the reference and input that are thereafter nonlinearly transformed and inverse Fourier transformed by a processor to determine the presence or absence of a correlation spike indicative of authenticity. A spatial light modulator (SLM) can be used as an input or reference and preferably is a liquid crystal panel having pixels or elements whose phase or grey scale intensity can be selectively controlled by a processor. The SLM can be used to display a biometric pattern, preferably scanned in real time from a person, that is correlated against an input or reference that can comprise a label on a card, a tag, or another object.
