Abstract:

Sea ice is one of the important natural disasters.A new method based on optical fiber Fabry-Perot sensor for ice strain measurement was proposed to meet the needs of ice strain monitoring.A high sensitivity optical fiber Fabry-Perot pressure sensor with thin-film structure was realized by means of pressure assisted arc discharge method,and the sensor was encapsulated by metal tube /PDMS /AB epoxy glue combination method.On this basis,the static internal strain characteristics of ice in the process of melting and freezing during -15℃~0℃ was studied.Experimental results show that this proposed thin-film fiber Fabry-Perot pressure sensor has good sensitivity characteristic in ice strain monitoring,it is believed of great value for the monitoring of remote distributed sea samples.

Key words: fiber Fabry-Perot sensor, static ice strain monitoring, thin film structure, pressure-assisted arc discharge
