| 摘 要： | 针对高精度多自由度位移同时测量问题，利用光斑位置变化方法设计了一种基于单面阵（CCD，Charge—Coupled Device）三维平移测量系统。系统采用两路准直（LED，Light—Emitting Diode）光束作为测量基准，由单面阵CCD探测光斑图像，图像经处理后可获得光斑位置信息，根据光斑位置变化推算出被测物体三维平移变化量。在实验室环境下构建了二维实验系统，模拟测量X向和Z向的平移变化，结果表明，X向平移测量精度优于±1μm，Z向平移测量精度优于±2μm。系统具有非接触、体积小、精度高的特点。

| Abstract: | High-accuracy simultaneous measurement of multiple degrees of freedom is widely applied and deeply studied.Using light spot position variation method,a measurement system of 3-D(three dimensions,X,Y and Z direction) translational motion based on single area array Charge-Coupled Device(CCD) is designed.Two collimated Light-Emitting Diode(LED) light beams are used as measuring basis.The light spots are captured by the area array CCD to locate their position.Based on the deviation of the position,3-D translati... |
