OPTICAL SENSING APPARATUS

摘要

The present disclosure provides an optical sensing apparatus for measuring a change in a first property. The optical sensing apparatus comprises first and second optical fibre portions and a sensing region for exposing both the first and second optical fibre portions to a change in an applied force. The force is, or is related to, the first property and has a component that is transversal to the optical fibre portions. The apparatus further comprises a holder for holding the first and second optical fibre portions in the sensing region. The first and second optical fibre portions are arranged relative to each other such that the change in the force results in a first change of an optical property of the first optical fibre portion and in a second change of the optical property of the second optical fibre portion and wherein the first change differs from the second change.

1. An optical sensing apparatus for measuring a change in a first property, the optical sensing apparatus comprising:
first and second optical fibre portions; a sensing region for exposing both the first and second optical fibre portions to a change in an applied force, the force being associated with the first property and having a component that is transversal to the optical fibre portions; and a holder for holding the first and second optical fibre portions in the sensing region; wherein the first and second optical fibre portions are arranged relative to each other such that the change in the force results in a first change of an optical property of the first optical fibre portion and in a second change of the optical property of the second optical fibre portion and wherein the first change differs from the second change.
