Abstract

Modal noise : distortion of signal caused by interference between different modes, is a well-knownproblem in multimode fiberoptic communication192). Being sensitive to mechanical distortion of the fiber, however, this phenomenon has been used to advantage in the sensing of sound3) and liquid flow4). In this paper, results of our experimental studies on a kilometer-long fiberoptic line sensor based on intermodal interference are presented. It is shown that practical distributed sensing system, useful in security applications, can be easily constructed from such lengthy line sensors.
