A two-dimension measurement system is produced in this paper. The system modifies the conventional measurement method. The constituents of hardware and its operating principle of the new automatic two—dimension device are introduced in the paper. The dynamic performance of the system is analyzed by means of theory analysis and the system identification of the test data. Various error elements that afect the measurement results are also analyzed, and the static errors of the system are corrected and compensated. The software development of the entire system is introduced in detail in this paper, at will. The anticipant result of the assignment is: the measurement accuracy can reachO. 09mm in the gamut range, and the linearity is 0.1%，The structure of the measurement system is simple and compact，and the dynamic, response is fast. The system can be applied extensively in the field of measurement and control integration Keywords: two-dimension measurement system Grating Stepper motor TOC \o 1-5 \h \z HYPERLINK \l bookmark2 \o Current Document \h 第一章绪论 1 HYPERLINK \l bookmark3 \o Current Document \h 1.1问题的引出 1 HYPERLINK \l bookmark4 \o Current Document \h 1.2国内外的研究现状 1 HYPERLINK \l bookmark5 \o Current Document \h 1.3本论文研究的内容、解决的问题及预期效果 2 HYPERLINK \l bookmark6 \o Current Document \h 第二章二维测量系统及硬件配置 3 HYPERLINK \l bookmark7 \o Current Document \h 2.1系统的总体结构及工作原理 3 1. 1系统的总体结构 3 1.2系统的测量原理 4 HYPERLINK \l bookmark8 \o Current Document \h 2.2二维测量系统的工作台设计 4 HYPERLINK \l bookmark9 \o Current Document \h 2.3传感器的选择 5 2. 3. 1各种测量仪器的特点 5 2. 3. 2选用光栅尺的原因 6 2. 3. 3光栅尺莫尔条纹位
