Paper Abstract

The optochemical sensor network: uses side-polished optical fibre elements with wavelength multiplexed fibre-pptic Bragg gratings. The refractive index of the overlay material near to the surface of the polished fibre influences the propagation constant of the guided fibre mode and, thereby, decides the spectral position of the Bragg reflection. The sensor network can be applied for on-line measurement of spatial material distributions and for process control in chemical and biochemical technology.
