灵敏度可调型光纤FBG倾角传感器研究
Study on Sensitivity-adjustable Fiber Bragg Grating Obliquity Sensor
摘要
Abstract
A new sensitivity-adjustable fiber Bragg grating (FBG) obliquity sensor based on the deformation theory of the constant-section beam is described. The obliquity sensor can achieve the measurement of object' s angle by the way that the FBG experiences the deformation of the constant-section beam due to the change of object' s angle, and corresponding FBG obliquity measuring system was set up. Experimental results show that the measuring range is ± 35 °, the highest sensitivity is 56. 93 pm/( ° ) ,the measurement accuracy is 0. 02° , and the sensor sensitivity can be adjusted by altering the size of the constant-section beam.关键词
