Laser torquemeter - a new instrument

journal contribution
posted on 2015-12-07, 14:17 authored by T.H. Wilmshurst, Steve Rothberg, Neil A. Halliwell
A noncontact torquemeter is described whose operation relies on the periodicity of the dynamic laser speckle pattern backscattered from a rotating shaft. At 1800 RPM, some 100 time-resolved torque readings per cycle are possible to an accuracy of approximately 1' of shaft twist. In addition there is inbuilt immunity to shaft speed fluctuations and whole body vibrations.
