Abstract

The fibre optic displacement sensor described is capable of measuring displacements in the millimetres to metres range. It is based on multimode fibre and connectors, uses an LED source and is insensitive to changes in attenuation in the cables and connectors used. The output is conveniently in the form of an electrical frequency. The theory is discussed and preliminary experimental results are presented.
