光笔式无导轨三坐标测量系统的研究

Study on No Guide 3D-Coordinate Measurement Technology Using Light-Pen

提出一种非正交系统(俗称无机械导轨),利用位置敏感探测器PSD交汇成像实现三坐标测量,其测量头为一支带有点光源的笔,故称“光笔式无导轨三坐标测量系统”。文章阐述了该系统的结构设计理论及测量原理。

A novel no guide 3D coordinate measurementtechnique is proposed. A 3D coordinate measurement system with three sets of PSD devices used to realize intersection converge imaging is introduced, which is called as the light pen type of measurement system because the measuring head is made in a pen shape with several light sources. The principles of structure design and measurement are presented.
