FIBER OPTIC SENSOR USING TRANSMISSIVE GRATING PANEL AND MIRROR

Abstract

Disclosed herein is a fiber optic sensor using a transmissive grating panel and a mirror, in which displacement resulting from a temperature change in the external environment or a behavioral change in an object to be measured is measured using a transmissive grating panel, a reflection mirror and an optical fiber, and then enables various measurements to be taken of the temperature change in the external environment and the behavioral change (displacement, pressure, vibration or acceleration, etc.) in the object on the basis of the measured displacement.
