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 non-orthogonal system (commonly referred to as “no mechanical guide rail”) is proposed, which uses coordinate intersection of PSD and position-sensitive detector to realize CMM. The measuring head is a pen with a point light source. Therefore, ". The article expounds the system structure design theory and measurement principle.
