Abstract
In ocean optics, salinity is an important inherent optical parameter to be measured. In the field of optics, refractive index (RI) is closely related to salinity. Through the real-time detection of the refractive index, we achieved the purpose of underway monitoring the salinity of seawater. We designed a refractive index measurement system based on optical total internal reflection. In this system, the detecting precision of the refractive index of the sea water reached 10-4. Through the conversion of the refractive index, we achieved in-situ measurement of the salinity. In 2016 summer, we accomplished a successful underway measurement in China Yellow Sea. The trends of the results from refractive index are basically agreed with the salinity measurements from electrical conductivity.
