Abstract

A fiber-optic turning reflective sensor is introduced. In this technique, the output of a pair of fibers are determined separately and their intensity ratio is used for measuring the relevant physical quantities. It is shown theoretically that many factors such as the variation of the source intensity, the variation of the reflectivity on the reflecting surface, and the difference in the fiber losses which could affect the measuring results in the ordinary method are eliminated in this technique. This is also confirmed by the experiments given in the paper. Based on this sensing technique, a prototype pressure sensor has been made and was used for testing.
