The phenomenon of cross-talk between optical fibers is usually used in the development of optical directional couplers. Subject of this paper is the description of a versatile sensor using this phenomenon and its various applications in liquid level sensing, refractometry, thermodletry etc. 111. The sensing element, which is also a part of the transmitting and receiving fibers, can be located either between or at the end of these fibers. The configuration can be chosen according to the type of application and mechanical construction. It is possible to measure the cross-talk signal independent of transmission losses and also to monitor failure of the system due to breakage in the optical or electrical circuit.
