摘要：

A fiber optic sensing system for simultaneous measurement of temperature and salinity based on fiber Bragg grating technology is presented. The fabrication process, which relies on chemical etching of the fibre, is described and its performance is evaluated. Theoretical and experimental results are given, which are summarized on the obtained resolutions of +/-0.06degreesC/ rootHz and +/- 0.2parts per thousand./ rootHz for temperature and salinity, respectively.
