Paper Abstract

Mang analysis have been done on the optical fiber position sensor based on intensity modulation technique. In this paper we present an analysis on Optic-Fiber-Array Sensor with a shutter wheel as intensity modulator, which can work on large dimensional measurement such as length or rotation angle with high sensitivity, accuracy and S/N. Different arrangements of optic fiber array versus shutter wheel are analyzed, and so are two signal processing methods, Switch-Digital Processing Method and Analog-Digital Processing Method. The angle sensitivity of the sensor can reach up to 10-6 (in rad.) and the S/N is higher than that of the Moare Technique. At the final, experiment results are shown.
