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.
