A comparison of time and frequency domain-based approaches to laser Doppler vibrometer instrument vibration correction

When laser Doppler vibrometers are used in the presence of ambient vibration, it is essential to compensate for the additional vibration signal content. In practice, compensation is realised by independently determining the instrument vibration and subtracting it from the erroneous measurement. When...
