Abstract
An optical fibre pressure sensor in which two or more lengths of side-hole fibre (1, 2) are joined together at their ends, in which at a joint (3) the two pieces are rotated relative to one another around their common longitudinal axis, in which one or more lengths of side-hole fibre have their holes (5) sealed, and in which one or more lengths of side-hole fibre have their holes (4) exposed to the same pressure as is external to that length of fibre.
Claims12
An optical fibre pressure sensor in which at least two lengths of side-hole fibre are joined together at adjacent ends of the lengths of side-hole fibre, in which at a joint the two lengths of side-hole fibre are rotated relative to one another around a common axis, in which at least one length of side-hole fibre has its side-hole sealed, and in which at least one length of side-hole fibre has its side-hole exposed to a pressure which is the same as a pressure which is external to that length of side-hole fibre.
