Abstract

A portable and practical fiber-type sensor, with which can determine the refractive index and the concentration of the liquid, has been designed and realized. The method combines simplicity of structure, facility of operation, wide range of measurement and low price. It can be used either by immersing the liquid or by pouring one drop of liquid into the sensing head. The measuring resolution of the refractive index is 1.41 X 10^-4 for the refractive indices of 1.33 - 1.70, and the measuring resolution of the concentration is 2.67 X 10^-4 for the salt solution and the sugar solution.
