Topic: Arbitrary path tracking laser Doppler vibrometry (LDV) for remote vibration measurements from light structures
Laser Doppler vibrometry (LDV) is now readily accepted as an alternative technology for the measurement of surface vibrations with special benefits for a wide range of applications. Scanning LDV, where the probe laser beam orientation is rapidly manipulated, enables the rapid surveying of a vibrating area of interest. Synchronisation of the scanning beam with a continually moving system enables the tracking of that system. Where such movement is arbitrary or not pre-determined, additional instrumentation is required to realise this.
This project will involve the research and development of a novel arbitrary path tracking LDV and its application to a range of application areas of interest, such as: (i) the tracking of insects moving around in a petri dish, such that the low level vibrations they generate during locomotion can be determined; (ii) the tracking of a vibrating flapping wing system in a wind tunnel to understand the dynamics of such structures and their impact on fluid-structure interaction, and (iii) the tracking of sports equipment (bats and balls) (eg) during a shot where the striking implement and/or ball vibration is critically important to determine and engineer to produce a quality performance outcome and/or player experience.
