Advanced time average holographic method for measurement in extensive vibration amplitude range with quantitative single-pixel analysis

摘要

In this paper we propose a time average digital holographical arrangement employing frequency shift of reference wave and its phase modulation. It results in Phase Modulated Frequency Shifted Time Average Digital Holography PMFSTADH method. This method has a potential to extend currently using frequency shifted time average digital holography to possibility of numerical analysis. It is primarily useful for measurement of great or very small amplitudes of vibration. Moreover we use acusto-optical modulators to realize frequency as well as phase modulation so we need no additional hardware in our experimental setup.
