Background: Laser Doppler vibrometry is now a well established technique enabling noncontactvibration measurements in the most challenging of environments. Rotor vibrationmeasurements are often highlighted as a major application of Laser Vibrometers due to theirnon-contact operation and inherent immunity to shaft run-out.Method of Approach: In such measurements, resolution of the individual axial and torsionalvibration components is possible via particular arrangement of the laser beam(s). Resolutionof the radial or pitch / yaw vibration components, however, can only be achieved by essentialpost-processing of the data from simultaneous orthogonal measurements.Results: This paper describes the principle and rigorous examination of a novel, dedicatedresolution algorithm enabling, for the first time, real-time post-processing of the outputs fromstandard commercial instruments.Conclusions: The system performed well, even in the presence of noise and other typicalmeasurement errors, and was implemented successfully in an engine vibration study.
