    摘要: A non-scattering light pipe includes a transition surface between a first side wall and an input surface and a second side wall and the input surface. The transition surface is arranged to substantially obscure the corner interfaces between the first and second side walls and the input surface such that in the corner formation any imperfections therein are not imaged into the output. Most preferably, the transition surface is optimized to provide a substantially uniform light intensity distribution. A light pipe in accordance with the preferred embodiments of the present invention is further arranged to couple to a linear light source, such as a cold cathode fluorescent light (CCFL). The light source is arranged such that dim areas, i.e., areas of the light source having non-uniform intensity, are not disposed adjacent the input surface.

    摘要: A method of rapid prototyping a lighting system which is at least one of folded path and multifaceted includes determining output power of the lighting system by calculating phase space density. A method of rapid prototyping a lighting system comprises ray tracing the lighting system, determining photometric quantities which describe the lighting system based on the ray tracing step, and providing a stereoscopic three-dimensional rendering of the lighting system based on the determining step. The three-dimensional renderings reveal any hidden pseudo-image artifacts in a lighting system before the lighting system is actually fabricated. A computer system for rapid prototyping a lighting system comprises a plurality of slave processors networked to a host processor. The slave processor and the master processor cooperate to ray trace the lighting system, and the slave processors perform homogeneous independent tasks. The computer architecture allows the homogeneous independent tasks to be distributed to the plurality of slave computers, so that the overall amount of time required to perform the tasks is drastically reduced. The amount of computational time required to generate useful information about a prototype lighting system is thereby reduced.

    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: 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.
