Abstract
The authors describe modifications to the method of reference beam phase modulation as applied to time-averaged electronic speckle pattern interferometry. The modifications enable measurements of vibration amplitudes at frequencies in the megahertz region to be made semi-automatically across the whole surface of an object.Keywords
