Abstract

In an aspect of the invention there is provided fluid discrimination apparatus comprising fluid inspection means, the fluid inspection means comprising a light source (111), a detector (113) and an optical element (121), the inspection means being operable to direct a beam of light from the source (111) through the optical element (121) to an inspection surface (125) of the optical element (121) and to detect by means of the detector (113) light scattered back through the optical element (121), the apparatus being operable to determine whether a fluid (135) in contact with the inspection surface (125) corresponds to a fluid having a prescribed refractive index characteristic responsive to light detected by the detector (113). The apparatus may be useful in applications in which liquid fuels are handled, and may be used for detecting a misfuelling event.
