1. Cavity enhanced optical sensing
Abstract : An optical cavity comprises a set of mirrors between which light can be reflected a number of times. The selectivity and stability of optical cavities make them extremely useful as frequency references or discriminators. READ MORE

3. Optical Diagnostic Techniques Applied in Practical Combustion Devices and Processes
Abstract : Optical measurement techniques have proven to be useful tools for studying combustion-related phenomenon. The fact that the techniques are optical facilitates performing the measurements without impinging upon the measurement object, such as the combustion event that can be involved. READ MORE

4. Towards a new sensing strategy for measuring paper pulp properties : a combination of ultrasonic and optical measurement techniques
Abstract : In the manufacturing process of paper the mass fraction and material properties of the fibres in the pulp suspension are important for the strength and quality of the finished product. The properties of the fibres in the pulp suspension that enters the paper machine is not well understood and therefore an adequate prediction of the strength and quality of the finished paper is not possible.

5. Fibre-Optic Displacement and Temperature Sensing Using Coupling Based Intensity Modulation and Polarisation Modulation Techniques
Abstract : Optical fibre sensors are employed in the measurements of a number of different physical properties or for event detection in safety and security systems. In those environments which suffer from electromagnetic disturbance, in harsh environments where electronics cannot survive and in applications in favour of distributed detection, fibre-optic sensors have found natural areas of use.
