Abstract
PURPOSE: To highly correctly detect the position in the short range and the fine displacement in the long range with the use of a simple and inexpensive device by utilizing the fact that the quantity of the incident light, which comes agin into the leading end of an optical fiber, is dependent upon the distance between the leaking end of the optical fiber and a reflecting mirror, i.e., the displacement information.
