Abstract

This invention relates to a tapered fibre optic (12), a sensor (10) utilising the fibre optic, and a method of use. The tapered fibre optic has a first end part (14) with a first cross- sectional dimension, a second end part (16) with a second cross - sectional dimension, and a central part (20) between the first end part and the second end part, the central part having a cross - sectional dimension which is smaller than the first and second cross - sectional dimensions. The central part of the fibre optic has a predetermined curvature and is adapted to be immersed in a liquid (26), the total internal reflection of the fibre optic depending upon the liquid. The sensor comprises the tapered fibre optic, a light source (22) and a light detector (24). The sensor can be used to determine changes in the liquid level, or changes in the surface properties of the liquid, or of a monolayer floating on the surface of the liquid.
