Low coherence fibre interferometry with a multi-wavelength light source

Vasiliev, Mikhail (2001) Low coherence fibre interferometry with a multi-wavelength light source. PhD thesis, Victoria University.


This thesis describes the results of study of the multi-wavelength low coherence fibre interferometry. The development and performance of the all-fibre interferometric measurement systems utilising multi-wavelength combination sources are described. Principal aspects of the low-coherence sensor interrogation scheme are analysed in order to substantiate the development of fibre sensors with a particular configuration that employs a reflection-type Fabry-Perot as sensing interferometer and a reflection-type Michelson as receiver interferometer. The background on the choice of an optimised signal processing scheme and data processing algorithms is given. Predictions were made during this work regarding the achievable measurement resolution and speed, together with the analysis of the limitations of the chosen measurement scheme.
