TL;DR: In this paper, a fiber laser hydrophone with enhanced sensitivity is demonstrated, where two diaphragms with a hard core fixed at each center are used as the sensing element.

TL;DR: In this article, a novel fiber Bragg grating (FBG) pressure sensor based on the double shell cylinder with temperature compensation is presented, in which a sensing FBG is affixed in the tangential direction on the outer surface of the inner cylinder, and another FBG was attached in the axial direction to compensate the temperature fluctuation.

TL;DR: This Letter presents a static strain demodulation technique for FBG-FP sensors using a suppressed carrier LiNbO(3) (LN) optical single sideband (SSB-SC) modulator, which can solve the problem of the frequency-swept nonlinearity effectively.

TL;DR: An all-metal double metal diaphragm-based optical fiber accelerometer with low transverse sensitivity is proposed and experimentally demonstrated in this paper, where the theoretical analysis is given based on the electro-mechanical theory.

TL;DR: The advantage of the proposed algorithm over the traditional methods based on fiber Bragg Grating (FBG) include the capability of having higher strain resolution for AE detection and taking into account two different types of AE source for location.
