Paper Abstract

This paper introduces a relatively simple multimode fiber optic sensor built for on-line use and a package that multiplexes two fiber sensors. The multiplexing is achieved by the random nature of the multimode fiber output intensity variation (so called speckle pattern). The demultiplexing is performed by a neural network. The dynamic range of each sensor is 0.8- 120 micrometers over an effective length of 11 m. The sensors operate in 68-94 degrees F.
