Abstract

PURPOSE:To make use of diffraction effect of light and accurately detect the vibration waves without the effect of noise by producing distortion waves within a light transmittable propagating medium of sound with the vibration waves transmitted from the vibration receiving part of a vessel and making photo-electric conversion of the same with the waveguide of light.
