They are designed to detect and quantify physical parameters like pressure, displacement, and vibration by monitoring changes in the light transmission characteristics of an optical fiber subjected to controlled bends. 1Institute of Microengineering and Nanoelectronics (IMEN), Universiti Kebangsaan Malaysia (UKM), 43600 Bangi, Malaysia. Intensity modulation induced by microbending in multimode fibers is considered as a transduction mechanism for detecting environmental changes such as pressure, temperature, acceleration, and magnetic and electric fields. In the article, a new idea has been brought out to study a traditional optical question, that is, fiber sensor was taken accounted as an information system, which has been analyzed with the information theory.
