Simultaneous optical interrogation of multiple tuning fork resonators using range-resolved interferometry. IEEE Sensors Conference 2017, IEEE Sensors 2017, 29 October - 1 November 2017, Glasgow, UK.978-1-5090-1012-7http://dx.doi.org/10.1109/ICSENS.2017.8233881https://dspace.lib.cranfield.ac.uk/handle/1826/12885In a proof-of-principle experiment, the vibrations of a set of three tuning folk resonators are simultaneously interrogated along a single optical beam using range-resolved interferometry. Measurements with noise standard deviations in the nm levels over bandwidths of many kHz are possible. In addition, a high degree of environmental noise rejection is inherently achievable because only differential measurements between the vibrating tuning folk prong pairs are evaluated. Employing only highly coherent, robust and cost-effective diode lasers, this approach could be useful for a wide range of mechanical sensor interrogation tasks.enAttribution-NonCommercial 4.0 Internationalhttp://creativecommons.org/licenses/by-nc/4.0/Optical interferometryOptical sensorsMechanical sensorsSensor systems and applicationsConference paper
