【摘要】：凭借多媒体技术的发展,显示技术上升到了一个更加重要的位置,随着移动终端设备的普及以及显示技术的不断进步,激光扫描投影显示技术正在一步步走进人们的生活中。激光扫描投影显示技术具备传统投影显示技术所不具备的独特优点,包括大色域、高效率、长寿命,同时可以在任何不规则平面上投影任何分辨率图案。但是目前的激光扫描投影显示技术,还有其难以克服的技术难点,包括振镜器件制作和显示控制。目前在国外已有少数生产商以及研究机构制作出微型激光投影器件,不过该技术被他们所控制,这些单位一般只提供投影仪器成品,而在国内还没有一套成熟的技术能够解决相关难题。最近国内已有科研单位制作出二维谐振的MEMS扫描镜,本论文便主要针对二维谐振的MEMS扫描镜作出一系列的研究,先从理论上论证基于二维谐振振镜的激光扫描投影显示技术完全可行,并在MATLAB仿真中给出实现思路,接着从显示技术的一些关键参数入手,对这些参数进行定量的分析,最后在实验中给出具体实现的系统原理,从理论、仿真和实践的角度提出了基于二维谐振振镜的李萨如图式激光扫描投影系统。同时在第五章给出了基于二维谐振振镜的扩展应用,标示着二维谐振振镜与激光扫描投影显示技术未来不可估量的巨大发展潜力。
[Abstract]:With the development of multimedia technology, display technology has risen to a more important position. With the popularization of mobile terminal equipment and the continuous progress of display technology, Laser scanning projection display technology is coming into people's life step by step. Laser scanning projection display technology has unique advantages that traditional projection display technology does not, including large color gamut, high efficiency, long life. At the same time, any resolution pattern can be projected on any irregular plane. However, the current laser scanning projection display technology has its difficult technical difficulties. Including vibroscope device fabrication and display control. At present, a small number of manufacturers and research institutions abroad have produced micro laser projection devices, but the technology is controlled by them, and these units generally only provide projectors with finished products. However, there is not a set of mature technology to solve the related problems in our country. Recently, there have been many research institutes in China to produce two-dimensional resonant MEMS scanning mirror, so this paper mainly focuses on two-dimensional resonant MEMS scanning mirror. It is proved theoretically that the laser scanning projection display technology based on 2-D resonator mirror is feasible, and the realization idea is given in the MATLAB simulation. Then, some key parameters of the display technology are analyzed quantitatively. Finally, the system principle is given in the experiment. From the point of view of simulation and practice, a laser-scanning projection system based on two-dimensional resonant mirror is proposed, and the extended application based on two-dimensional resonant mirror is given in Chapter 5th. It indicates the great potential of two-dimensional resonant mirror and laser scanning projection display technology in the future.
