Abstract

PURPOSE:To measure the quantity of displacement with high accuracy by setting the interval between the light projection and reception surface of a probe and a reflecting plate previously without any error. CONSTITUTION:When the reflecting plate 18 vibrates on detecting external vibrations and the interval S between the light projection and reception surface 12b and a body 18 to be measured varies, the ratio of the quantity of light reception to a light emitting element 20 varies, so the vibration quantity of the reflecting plate 18 is measured from the variation quantity of the ratio and the measurement result is displayed on a display device 8. Here, W is the waveguide width of the light projection and reception surface 12b of the probe 14, S is the interval between the light projection and reception surface 12b and reflecting surface 18, and theta is the opening angle of the light projection and reception surface. When the reflecting plate 18 is within a linear area of S>=W/(2tantheta), light which is emitted by the light projection and reception surface 12b of the probe 14 and reflected by the reflecting plate is incident regularly on the light reception surface 12b.
