Teaching/Work responsibilities

  • Coordination of Optics Laboratories
  • Program leader for undergraduate and Honours Applied Physics degrees

Research Interests

Application of optical techniques to measurement and sensing applications, including

  • Holography
  • Interferometry
  • Speckle Correlation and Interferometry
  • Fourier Optics
  • Digital Image Processing
  • Photometry
  • Spectrophotometry
  • Colorimetry
  • Polarimetry
  • Optical Design
  • Laser Applications

Research Projects, Consultancy and Student Project

  • 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.
  • Optical characterisation of surfaces and thin films:
    The reflecting properties of materials are measured to give information on their composition and structure. The techniques of reflectance spectroscopy and spectroscopic ellipsometry are used.
  • Consultancies:
    Advice and custom measurement service provided to local industries in the areas mentioned under Research Interests.
