Abstract

A new method to compute the target photometric variables of non-imaging optical systems is presented. The method is based on the phase space representation of each surface that forms the optical system. All surfaces can be modeled as detectors of the incident light and emitters of the reflected light. Moreover, we assume that the source can only emit light and the target can only receive light. Therefore, one phase space is taken into account for the source and one for the target. For the other surfaces both the source and target phase spaces are considered. The output intensity is computed from the rays that leave the source and hit the target. We implement the method for two-dimensional optical systems, and we compare the new method with Monte Carlo (MC) ray tracing. This paper is a proof of principle. Therefore, we present the results for systems formed by straight lines which are all located in the same medium. Numerical results show that the intensity found with the ray mapping method equals the exact intensity. Accuracy and speed advantages of several orders are observed with the new method.

二维反射光学系统的相空间反射线映射

提出了一种计算非成像光学系统目标光度变量的新方法。该方法基于形成光学系统的每个表面的相空间表示。所有表面都可以被建模为入射光的探测器和反射光的发射器。此外，我们假设光源只能发光，目标只能接收光。因此，对源和目标分别考虑一个相空间。对于其他曲面，源相空间和目标相空间都被考虑。输出强度是根据离开光源并击中目标的光线计算的。我们将该方法应用于二维光学系统，并与蒙特卡罗(MC)光线跟踪方法进行了比较。这篇论文是一个原理证明。因此，我们给出了在同一介质中由直线组成的系统的结果。数值结果表明，用光线映射法得到的光强等于精确光强。实验结果表明，该方法在精度和速度上具有一定的优势。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
