摘　　要：制作了一个基于电感传感器原理的微小位移测量装置,将测量结果与光杠杆的测量结果相比较,发现用电感传感器测量微小位移时,灵敏度、线性度和测量范围相互制约。但在一定范围内,它的测量精度比光杠杆的更高。According to the principle of inductance transducer, an installation of measuring micro-displacement was made, Comparing the result with that we measure in the optical lever,it was found that the scope of measurement is restricted with the sensitivity of measure when measuring micro-displacement by inductance transducer,but it is more exact than the result measured by the optical lever in some range/

关 键 词：微小位移 电感传感器 光杠杆
