摘要
动态红外场景投影(DIRSP)技术是考察和评估红外成像测量跟踪系统性能指标的主要方法。本文回顾了国内外DIRSP技术的发展现状及应用,概述了几种主要的DIRSP技术及其特点。在详细介绍数字微镜器件(DMD)的工作原理及机械结构的基础上,总结了灰度等级控制的方法及其特点。通过对3种数字光处理(DLP)显示系统投影原理的对比,指出了各自的特点和应用场合。重点分析了基于DMD的DIRSP系统-微镜阵列投影系统(MAPS)的工作原理、系统结构、性能指标及技术优势,并讨论了将DMD应用于DIRSP所采用的6大关键技术。最后,结合DIRSP技术的应用背景和国内外研究现状,对下一步的研究工作做了展望。
Abstract
Dynamic Infrared Scene Projection(DIRSP) technology is a major method to evaluate the performance of infrared imaging measurement and tracking systems. The developments and applications of DIRSP technology at home and abroad are reviewed in this paper. Some of the popular DIRSP technologies and their characteristics are provided, then the operating principle and mechanical structure of a Digital Micromirror Device(DMD) are given. A new projection display technology based on DMD called Digital Light Processing(DLP) is briefly introduced, which can be divided into three types according to the number of DMD chips contained. The different features and applications of the DLP are also described. Furthermore, this paper lays particular emphasis on a DIRSP system based on DMD, namely, Micromirror Array Projector System(MAPS). It analyzes its operating principle, basic design, performance capabilities and technical advantages and discusses the key technical issues to be used as a DIRSP. In the end, based on the application background and research status of DIRSP, it presents the following step of research work.
