Abstract A four‐channel fiber loop ring‐down pressure sensor with temperature compensation based on neural networks is described.This makes use of the principle time division multiplexing, which consists series and parallel loops. The laser pulses from four‐channels can be acquired by only one detector four values are measured synchronously in our experiment. Taking mode dispersion multimode into consideration, maximum multiplexing number discussed. In addition, has been successfully used experiment, to eliminate disturbance environmental temperature. © 2010 Wiley Periodicals, Inc.
