Abstract

A contact fiber displacement sensor is introduced. According to the principle of reflected intensity modulation, the displacement can be measured by detecting the light intensity with a light detector. By use of the mirror fixed at the end of the measurement lever, the measuring result is not affected by the color, roughness, etc., of the object surface to be tested. The biggest measuring range of the sensor is 0.5 mm, and its nonlinearity is 0.5% by practiced test. The experiment curve is given.
