摘要：Salinity temperature and depth are the most important parameters in physical oceanography applications, because of they are the fundamental parameters of the seawater equation of state. In situ monitoring these parameters is of great importance for process control in manufacturing industries, protection of ecosystems, prevention of global warming, and especially underwater target monitoring and recognition. An all optical fiber CTD sensor used in seawater based on an OMC is demonstrated. And the OMC is fabricated by fusing and tapering two twisted conventional communication fibers based on the improved flame-brushing method. By monitoring the sensing dips, in situ measurement of salinity, temperature and depth (pressure) in seawater can be realized respectively. The all optical fiber CTD sensor demonstrated here show advantages of easy fabrication, compact structure, high sensitivity, low cost, and compatibility with the optical fiber system, which may find applications in multifunction optical sensors in ocean detections and other applications.
