In order to realize the precise measurement of acceleration by fiber Bragg grating,a novel double-cantilever beam fiber Bragg grating accelerometer is proposed.Firstly,the configuration and coating of the accelerometer were designed.Secondly,the principle of the fiber Bragg grating accelerometer was analyzed theoretically.The temperature response of FBGs and the acceleration response versus wavelength were analyzed.And the analytical formula of acceleration sensitivity was also deduced.Thirdly,t...
