主动式三维成像技术中的光学系统设计

计算机获取三维图像信息，主要有被动成像和主动成像两大类，在主动式成像技术中，照明光的设计是最重要的。本文提出的以彩虹光谱作为主动光源是近几年才提出的新方法。文中简述了该方法的原理，分析了几种常用的彩虹状光谱获取方法，重点对以棱镜为色散元件的光学系统作了分析、设计、计算，并给出计算结果和结论

Design of Optical System for Active 3 Dimension Image Technique

There are two kinds of method for computer to get 3 Dimension image:the passive image system and the active one.The design of illuminating light is one of the most important thing in active image system.The method using the rainbow spectrum as the active illuminating light discussed in this paper is recently proposed.In this paper,the principle of this method has been introduced roughly.Some methods to produce the rainbow spectrum have been analyzed.Mainly,the optical system using prism as a chromatic dispersion component has been analyzed and designed.The calculating results and conclusion have been given in the end.
