| 摘 要： | CCD作为一种光电转换器件，具有成本低、结构简单、扫描速度快、频率响应高等优点，越来越广泛地运用到测量领域。提出采用单色线阵CCD，以非接触的光学方式对角度信息进行编码调试，通过采集该信号利用数据处理模块，完成对图像信号的解调，实现角度值的测量。系统选用TSL1401和LPC2138为核心构成嵌入式测量系统，利用TSL1401采集信号，通过A/D传输到LPC2138中进行数据处理，最终得到角度值。系统通过光学的方式对角度进行测量，实现了非接触式测量。

| Abstract: | As a photoelectric converter, charge coupled device (CCD) is widely used in the field of measurement because of its low cost, simple structure, fast scanning speed and high frequency response. It was proposed to use a monochrome linear array CCD to encode and debug the angle information in a non-contact optical manner.By collecting this signal and using the data processing module, the demodulation of the image signal was accomplished, and the angle measurement was realized. The system used TSL1401 and LPC2138 as the core to form an embedded measurement system, which used the TSL1401 to collect signals, then transferred them to the LPC2138 for data processing through A/D, and finally obtain the angle values. Through the optical measurement of angle, a new method of non-contact measurement was realized. |
