Paper Abstract

We investigate the sensitivity improvement of fiber Bragg grating (FBG) sensors based on the optical attenuation-based weak value amplification (WVA). We successfully enhance the strain sensitivity of the FBG sensor based on the proposed WVA. The amplification factor (A) controlled by the optical attention is optimized to improve the sensitivity of the FBG sensing probe. The strain sensitivity of the FBG sensor using the proposed attenuation-based WVA is successfully enhanced by a factor of 2.73 compared with that without the WVA.
