Compensation Network for Multiple Intensity Modulated Optical Fiber Sensors

摘要

The accuracy of intensity modulation optical fiber sensors worsens greatly due to disturbances such as temperature fluctuation. This paper reports a novel m x n network compensation technique which can be simultaneously applied to many fiber sensors to minimize the degradation. We demonstrate a m x n network (m, n are integers and greater than 1) can compensate (m-1)(n-1) sensors at one time. Further analysis indicates that a m x n compensation network can be looked as the combination of (m-1)(n-1) four-node networks or three-node networks depending on its structure. Furthermore, its compensation potential is similar to elementary single-sensor networks.
