Abstract
Fiber Bragg grating (FBG) extensively employed in a variety of ways. In this paper, we designed an FBG sensor structure and introduced a novel method to determine the angle of vibration source. The performance of our sensor and the method were validated through experiments. We placed the sensor in a controlled water tank environment, utilizing a spherical object to generate vibration as the vibration source to stimulate the sensor. Through the FBG wavelength shifting data, the angle of ball was determined by the method. The results showed that the average deviation was only3 degrees, with an accuracy rate of 90%. Our finding demonstrate that this novel sensor has a better perception capability for minor vibrations and the angle determination method for the vibrating object has excellent accuracy.
