Abstract
In this paper, a quite simple and novel straightness measurement system was proposed. The laser beam from a single-mode fiber-coupled laser module is highly stable, and can be used as the reference line for straightness measurement. Base on the characteristics of a corner retro-reflector, the corner retro-reflector is used as the moving target in the straightness measurement system in order to reflect laser beam from measurement head back to it. In this way, there is no cable connection in the moving target, which is very convenient for straightness measurements in workshops. At the same time, relationship between voltage output from a quadrant photodiode detector and its displacement was analyzed theoretically, theoretical analysis shows a good consistence with practical measurement results. The accuracy of a micrometer at a distance of one meter was gotten by the system.
