Abstract

The extrinsic Fabry-Perot interferometer has been implemented before for the health monitoring of multi-computer communication networks. Such integrated sensor and communication system architectures can be extremely useful during the implementation of ITS traffic management centers. The same optical fiber can be modified to provide the necessary communication link, and the incorporated sensor can be used to monitor the health of the computer network, for providing a fault-tolerant architecture. However the signal to noise ratio, minimum detection reliability, and dynamic range of the interferometer are of primary concern in such an implementation. The main objective of this paper is to present an exact analytical and experimental evaluation of the extrinsic Fabry-Perot interferometer using Kirchhoff's diffraction formalism. The obtained results are compared with the conventional two-beam interference model, and proved to correlate better with the experimental results. Future applications of this optical interferometer in other ITS applications are also discussed.
