Abstract:
Strain sensing is important in numerous fields such as: structural health monitoring
[1], manufacture of composites [2], and civil engineering [3]. For many of these fields fibre optic based sensors have been utilised due to their numerous advantages, that
will be described in Chapter 2.
In this thesis I will described the production of three new fibre optic based strain
sensors: a microcavity based in-fibre Fabry-Perot etalon (Chapter 4), a birefringent
photonic crystal fibre (PM-PCF) based Michleson-interferometer (Chapter 5), and a
polarisation maintaining fibre (PMF) based Michleson-interferometer (Chapter 6).
In this chapter we will describe the aim of this work, the novelty of this work,
and how this work is presented in this thesis.
