摘要：

A novel intensity modulated fiber optic sensor (FOS) for liquid refractive index measurement is presented in this communication. The sensor principle is based on frustrated total internal reflection effect caused by refractive index change of a medium surrounding an optical fiber tip. Experimental results obtained for liquids of different refractive index confirm the sensor potential to act as a sensitive refractometer. (C) 2008 Elsevier B.V. All rights reserved.
