3/ 4 [ G] redundancy technique is applied in the design of the light pen system for the realization of self-calibration and self reparation when one light source is deficit for any reason.

The error of light pen system is less than 0.1 mm when the coordinate error of point source is(± 0.1 mm.)

点光源坐标误差为±0.1mm时，光笔系统误差≤0.1mm。

Recently, all the light pen CMM are pc-based systems, their image processing program and arithmetic program are all run in the computer.

目前，市场上的光笔三坐标测量机都是PC-Based系统，其图像处理程序和算法程序均在计算机中完成，相机只是负责采集图像和对图像进行简单的处理后上传给计算机。
