Thesis
Binetti, L. Investigation of fibre optic sensing techniques for the measurement of physical-chemical properties of liquids. (Thesis). Edinburgh Napier University

Single-mode optical fibre (SMF) sensors have been extremely useful in biomedical applications because of their small size and chemical inertness. Many optical fibre techniques have been used to measure the surface tension (𝛾) of liquids. However, due...
