Paper Abstract

The performance of experimental equipment built to evaluate a fibre optic method for reading instruments in remote locations is described. A retroreflecting encoder and a wavelength division multiplexing technique have been combined giving passive operation at the instrument and the need for only one fibre to read and transmit the data. A signal processing scheme for decoding a five digit decimal number using a microcomputer and means for compensating variations in source output and optical attenuations are discussed.
