Paper Abstract

With the advantages of simple structure, high speed, and high accuracy, a no guide 3D-coordinate measuring technique that using the photoelectric detectors with intersection converge imaging has the predominance in workshop measurement. Its measuring head is made in a pen shape with several light sources, which is called as the light pen. In this paper, the structure design and self-calibration of light pen system are analyzed, and the identifying way for multi-sources on light pen is present. The Laser-balls are offered to be the light-sources while the principles as well as fabrication are introduced. The light pen can insert and touch the points of inner surface in a deep hole. So the localization of CMM can be avoided by using the light pen with simple and deft structure.
