とを特徴とする光応用変位センサ。A sensor head in which a light-emitting optical fiber and a light-receiving optical fiber are bundled is provided opposite the displacement body, and the light emitted from the light-emitting optical fiber to the displacement body and the reflected light are transmitted to the light-receiving optical fiber. In a device that receives light and measures the amount of displacement of the displacement body based on a change in the amount of received light, two sensor heads are provided at two locations on the approach side and the far side with respect to the displacement of the displacement body, and the An optical displacement sensor characterized by being provided with a differential output means for extracting the difference in output between light-receiving side optical fibers and bars related to each sensor head.
