Regulation of the sensitivity of measurements in holographic interferometry of dynamic periodic structures

This paper discusses the features of the recording of a hologram of a periodic structure that make it possible when implementing a method of either real-time or double-exposure holographic interferometry to adjust the measurement sensitivity when investigating the temporal behavior of the periodic structure of an object. Experimental test results of the real-time holographic interferometry method, devised while studying the dynamics of two-dimensional periodic structures in time, are presented.
