A method is proposed for organizing deep-water refractometric studies and fiber-optic interference systems for precise monitoring of the absolute refractive index of sea water at depths up to 1000 m with measuring probes submerged independently or together with underwater equipment. 
Sea water refractive index measurement based on v-shaped cavity
In this paper, a new method for measuring the refractive index of seawater based on the V-shaped cavity is proposed. MATLAB software is used to simulate the V-shaped cavity based on the optical thinExpand
Comparative Study of Microfiber and Side-Polished Optical Fiber Sensors for Refractometry in Microfluidics
A simple theoretical analysis is undertaken to compare the change of guided mode index of microfiber and side-polished single mode fiber sensors to the refractive index of surrounding fluids. This isExpand
