WEIGHT AND DISPLACEMENT MEASURING DEVICE BASED ON FIBER BRAGG GRATING SENSORS
The present invention relates to a load and displacement measuring device based on an optical fiber Bragg grating sensor. The load and displacement measuring device based on the optical fiber Bragg grating sensor comprises: a body part on which an upright vertical block is installed on the upper surface; a plurality of horizontal blocks which are installed horizontally in the radial direction on the outer surface of the body part to receive load when the load is applied to the vertical block; a support block which is installed at an end of the horizontal block to allow the horizontal blocks to be mutually connected to each other and is formed to allow the lower surface of the support block to be positioned below the lower surface of the body part and the horizontal block; and an optical fiber grating sensor which is installed at two or more horizontal blocks among the horizontal blocks to have different wavelengths on either the upper surface or the lower surface, and measures the amount of displacement through a change in the wavelength when the load is applied. According to the present invention, tensile load and compressive load as well as load applied toward a lateral side can be precisely measured. Further, the height change and inclination of a measurement object can be precisely and easily measured using the measured load.
