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 reflected light from the light-emitting optical fiber to the displacement body is received by the light-receiving optical fiber. The apparatus for measuring the amount of displacement of the displacement body based on changes in the amount of received light is configured to selectively insert lenses having different positive or negative focal lengths between the sensor head and the displacement body.
