Testing of a recently developed digital holographic method for very small amplitude measurements

Popis výsledku v původním jazyce

This paper shows the comparison of a vibration measurement simultaneously performed with three different methods on the same sample. The aim of the paper is to experimentally prove the capability of a newly developed method for the measurement of vibrations with amplitudes in a nanometre range. The newly developed method is based on frequency shifted time averaged digital holographic interferometry combined with phase shifting and the phase averaging principle. The methods used as a bench mark are Doppler vibrometry performed with a commercial single point vibrometer and a single point interferometer in a Michelson construction which is improved with the lock in principle. The results have been compared and very good agreements between the results are shown.
