Title:
OPTICAL FIBER BRAGG GRATING-BASED SENSOR AND MEASUREMENT DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2016/052974
Kind Code:
A1
Abstract:
The present invention comprises: an optical fiber (2); an optical fiber Bragg grating (2a) formed on a part of the optical fiber; a tension application unit (9) arranged so as to apply a tension to the optical fiber Bragg grating; and a magnet unit (1) for driving the tension application unit, wherein the tension application unit is driven, when the distance to the magnet unit is equal to or less than a predetermined distance, and applies a tension to the optical fiber Bragg grating, thereby deforming the corresponding optical fiber Bragg grating and changing the wavelength of light that passes through the optical fiber.
