  • Torsion compensation system and compensation method for fiber Bragg grating curvature sensor
    Patent number: 12618663
    Abstract: The provided is a torsion compensation system and a compensation method for a FBG curvature sensor. The compensation system includes a FBG curvature sensor, installed on a scraper conveyor; angle sensors, including two and installed on both sides of the FBG curvature sensor, are configured to obtain the torsion angle of the FBG curvature sensor by monitoring the difference between the two ends of the FBG curvature sensor; a FBG string, arranged on the FBG curvature sensor to form a plurality of grating measuring points, is configured to perceive the center wavelength of the FBG curvature sensor; a FBG demodulator, coupled with the FBG string, is configured to convert the optical signal of the center wavelength perceived by the FBG string into an electrical signal; a computer, respectively coupled with the angle sensors and the FBG demodulator, is configured to eliminate the FBG wavelength variation caused by torsion.
