Research Interests and Activities

Within noise and vibration measurement and analysis, my specialism is in applications of laser technology for the measurement of motion and related parameters. My work in the areas of Laser Speckle Metrology and Laser Vibrometry is especially well recognised by academic peers and by the world’s foremost manufacturers of Laser Vibrometers with whom I have collaborated for well over 25 years. Three broad elements of the work with laser-based methods are advancing data interpretation capability with existing instruments, widening the range of applications of existing instruments and the development of new instruments. These interests encompass work of a very fundamental nature, for example in quantifying laser speckle effects and mathematical modelling of optical configurations, to work of a very applied nature such as the first-ever non-contact measurements of crankshaft bending vibration on a running diesel engine.

I also brought my expertise in noise and vibration measurement and analysis to early research activity in the area of sports equipment design, maintaining this contribution as the activity grew into the now well-established Sports Technology Institute. Particularly novel work has been undertaken in correlating noise and vibration measurements during impact with subjective perceptions in sports like tennis and golf.

  • Vibration measurement and analysis including modal analysis.
  • Laser Vibrometry including:
    • Measurements directly from rotors.
    • Laser speckle and elimination of pseudo-vibration.

  • Noise measurement and analysis.
  • Sports equipment design including: Impact modelling and analysis.
  • Noise and vibration related to "feel" of impact sports equipment.
