Application and research of the multi-parameters simultaneous measurement system in FBG sensors;

FBG sensors are embedded i.

Based on the strain,vibration and impact features of fiber Bragg grating(FBG)sensors,a fiber-optic intrusion alarm system using quasi-distributed FBG sensors is developed.

FBG sensor demodulation multi-wavelength detection design;

Because multimode fiber sensors and FBG sensors are simultaneously used in the system, the result of measurement is more reliable.

The FBG sensor′s pressure sensitivity that influenced by the metal-coated material and thickness was studied,and the relationship between them was rightly calculated.

Experimental study on early age property of high performance concrete by FBG strain sensor;

A fiber optic hydrophone with chaos;

Researching on the Experiment of Fiber Bragg Grating Hydrophone;

Calibration of hydrophone in a standing wave calibration system for dipole hydrophone;

Broadband matched field source localization in F-lake with a single hydrophone;

Aiming at the complex algorithm and the need of more elements in the estimation of underwater moving target with TMA and MFD,this paper presents a method of target moving parameter estimation based on the analysis on spectrum interference in shallow water,which can be used in a single hydrophone.

Based on a fast realization method for waveform cross-correlation, we have done an experimental study on broadband matched field source localization in F-Lake with a single hydrophone.
