Projects
- Digital speckle pattern interferometry: Laser illumination, video camera recording and digital image capture and processing are used to measure very small displacements, distortions and vibrations of objects. Applications to non-destructive testing of structures and materials are studied.
- Reflectometry and ellipsometry of surfaces and coatings: The reflecting properties of materials are measured to give information on their composition and structure.
- Applications of image analysis in the paper and packaging industry: Instrumentation is being developed to measure various properties of paper products, such as washboarding in corrugated cardboard.
- Thermal focussing by non-linear optical materials: Transient phenomena with possible sensor applications are being investigated both experimentally and theoretically.
