摘要
首次提出了一种所谓“差线栅位移传感器”,它采用与游标卡尺类似的原理 ,利用相对运动的两套标尺刻线数之差 ,得到更多的插值脉冲 ,达到提高分辨力的目的。这种传感器的参数选择对传感器的性能有重大影响 ,要考虑的因素和须遵循的规律比较独特。在此详细介绍了差线栅位移传感器的设计思想 。
It proposes for the first time a new sensor called differential grating displacement sensor. Based on the principle resembling that of vernier caliper, using the scale differential of two staves with relative motion, it can gain more impulses, and attain the goal of improving resolving power. The parameter choice of differential grating displacement sensor has a great effect on the performance of the sensor. It is comparatively special for the factors which need to be considered and the rules which need to be followed. The design idea, the work principle, and the parameter design rules of the sensor are introduced.
