This paper presents a frequency shifted time average digital holography technique for small mechanical vibration amplitude measurement and a novel single-pixel method for vibration amplitude distribution reconstruction. The reconstruction method is compared with results from common interpolating based technique used in holographic vibration analysis. Further the developed method is used for measurement of vibration amplitudes of a glass window in order to verify its reliability.
