【摘要】：数字光处理是一门以数字微镜为核心的光机电技术。过去数字光处理技术主要应用于投影显示,并凭借分辨率高、适应能力强等特点在市场上占有一席之地。现如今,随着该技术不断进步,其应用范围也不断扩大,例如时下热门的智能照明、3D打印等。不过,由于德州仪器并未公开该技术的核心资料,许多国内外的研究人员想开发和应用却无从下手。为解决上述问题,近几年来,本人对该技术进行了深入的研究与学习,结合具体的项目实践,设计了一个开源的数字光处理平台。首先,本文分析了数字微镜的驱动方法及交织算法原理,提出了分块的时间交织算法以及二维交织算法,并设计了相应的数字微镜仿真器。新算法可使数字微镜在刷新率、显示灰度和数据准确度上都有显著改善。接着,自主开发了数字光处理硬件平台。该平台以Spartan-6 FPGA为核心,配备高速高带宽DDD3内存(800MHZ),可提供多种视频图像接口。该平台和数字微镜子板分开设计,通过134对LVDS信号(800 MHZ)实现连接,可驱动多种型号数字微镜,增加平台灵活性。最后,开发与硬件平台匹配的软件程序。采用多种编程语言编写FPGA、MCU、蓝牙以及手机APP程序,实现手机端远程控制,进行人机交互。交织算法实现,DDR3控制和管理是FPGA设计中的难点。相比其他数字光处理平台,本平台灵活度更高,性能更强,应用范围更广。本文的成果也将为其他研究数字光处理的学者提供一些参考和启示。
[Abstract]:Digital light processing is a digital micro mirror as the core of the electrical and optical technology. Past digital light processing technology is mainly used in projection display with high resolution, adaptability to occupy a space for one person in the market. Now, with the advances in technology, its application scope is expanding, such as the popular intelligent lighting, 3D printing. However, because TI did not disclose the core information technology, many domestic and foreign researchers to the development and application of knowing where to start. In order to solve the above problem, in recent years, I conducted in-depth study of the technology, combined with the specific project practice, the design of a an open source digital light processing platform. Firstly, this paper analyzes the driving method of the digital micro mirror and algorithm principle, proposed block time interleaving algorithm and two-dimensional algorithm, and design phase The digital micro mirror simulator. The new algorithm can make the digital micro mirror in the refresh rate, display gray scale and data accuracy are significantly improved. Then, the independent development of the digital light processing hardware platform. The platform uses Spartan-6 FPGA as the core, equipped with high speed and high memory bandwidth of DDD3 (800MHZ), can provide a variety of video images interface. The platform and the digital micro mirror plate is designed separately, through the 134 signal of LVDS (800 MHZ) to realize the connection, can drive various types of digital micro mirror, increase flexibility and development platform. Finally, the hardware platform, software program. Using a variety of programming languages FPGA, MCU, Bluetooth and mobile phone APP, mobile phone remote control, human-computer interaction. Interleaving algorithm, DDR3 control and management is a difficult problem in the design of FPGA. Compared to other digital light processing platform, this platform more flexibility, better performance, more wide application scope in this paper. The results will also provide some reference and inspiration for other scholars who study digital light processing.
