摘要

微位移测量原理有许多种

利用偏振光的旋光效应是一种高效、简洁、精确的新方法。旋光效应是指单色线偏振光在沿光轴方向通过石英晶体时

透射出来的光的振动面会产生旋转的物理现象

其旋转角度与晶体厚度有关。用激光器、起偏器、石英晶体、千分尺等设计了一个微位移测试系统

测试表明:其测量精度能达到0.1μm

测量范围可达300μm

相对误差不超过±1%

能满足各种仪器仪表的微位移测量要求

可广泛应用于精密微位移检测系统中。

Abstract

It is a new way of high efficient

simple and accurate method which uses the optical rotation effect of polarized light

though there are many kinds of principles of the micro-displacement measurement.The optical rotation effect is a physics phenomenon that the jar face of the transmission light can produce rotary

when the linearly polarized light pass the quartz crystal on its axle direction

its spin angle relates to crystal thickness.A micro-displacement measurement system which uses laser light

the linearly polarized light

quartz crystal and the micrometer is designed.Test result shows that its measurement precision can achieve 0.1 μm and its measurement range 300 μm

relative error is less than ±1 %

it can meet micro-displacement measurement demand of all kinds of instrumentation

and can be widely used in precise micro-displacement measurement system.
