Abstract

A fibre-optic dark-field micro bend sensor capable of detecting 80% of the power loss of the brightfield and with a sensitivity of 1.0 10-11 ml/√Hz has been constructed. It was found that the micro-bend loss was independent of the number of bends for 3 or more bends. The deforming device was transparent and a detector was attached to its end.
