Research progress of fiber Bragg grating temperature sensors for ocean application

Effective deep sea exploration technology is an important way to obtain information about the marine environment and resources.It has also become the focus of current marine research.Marine temperature is one of the important physical quantity concerned in marine exploration.Fiber grating temperature sensor has been extensively used in aerospace,petrochemical and other fields due to its unique sensing advantages,but it has little penetration in marine environmental monitoring.This paper systematically reviews the basic principle,structure and performance of fiber Bragg grating compared with the traditional measurement methods.The latest research progress of fiber Bragg grating temperature sensors for marine exploration at home and abroad is also emphatically studied.Based on these materials,some suggestions on the future research direction of marine fiber Bragg grating temperature sensor are proposed.
