Paper Abstract

We designed and manufactured all optical fiber CTD to monitor ocean based on the sensitive characteristics about optical fiber grating. A series of works have done, including the calibration work for sensor in laboratory, simulated experiment outside and the local test of ocean parameter. The results we got show that the precision of temperature is 0.01℃ and of pressure is better than 0.1%, both of them overtake the secondary standard of GB/T23246-2009, moreover, close to the primary standard, and of salinity in laboratory has reached 708 pm/1% closely to the secondary standard. It is satisfied with the ocean monitoring requirements.
