The Michelson Interferometer has been the principal interferometer configuration for Optical Coherence Tomography (OCT) imaging. For OCT applications, in particular endoscopy, there may be polarisation induced signal ...

The following thesis is conceded with single mode fibre optic components which exhibit a wavelength selective transmission response. The response is achieved by mechanically polishing the side of a optical fibre in ...

This thesis investigated the repeatability of the overwrite long period grating (LPG) fabrication method and highlighted the advantage it offers in its ability to tune spectral features thus allowing the manufacture of ...

Monitoring pore pressure is important to understand and predict the mechanical behaviour of soil, helping engineers to assess the stability of slopes and built infrastructures. The instrumentation used to monitor pore ...

The subject of this thesis is the development of optical instrumentation for surface strain measurement of non-planar objects. The speckle interferometry technique of shearography is used to perform quantitative measurements ...

Microfluidic flows are an increasing area of interest used for “lab-on-a-chip” bioanalytical techniques, drug discovery, and chemical processing. This requires optical, non-invasive flow-visualization techniques for ...

This thesis describes the processes used to manufacture optical fibre tapers and tapered long period gratings (TLPGs) using a CO2 laser. A semi-automated system for fabricating adiabatic and non-adiabatic tapers with ...

The aim of the project was to develop the Fizeau interferometer configuration to take advantage of the benefits derived from its “downlead insensitivity” to temperature and polarisation fading. This sensing interferometer ...

The purpose of this thesis is to develop a rapid, sensitive and selective optical sensor for Campylobacter jejuni detection as it is the most common cause of foodborne illness in humans. The optical sensor platform was ...

The intrinsic stability of fibre optic based sensing systems offer a platform that is suited to hazardous waste detection in a wide range of environments. Over the last few years Cranfield University has been working on ...
