“…It should be said that the research of the high-frequency vibrations and their mode shapes, as in holographic and speckle interferometry, become difficult or impossible due to the fact that the contrast of the interference fringes decreases at high amplitudes and frequencies. It should also be noted that industrial application of speckle interferometry requires the establishment of specialized expensive stands, and furthermore, research may be carried out mainly with the small-sized constructions [5].…”

In this article, method for determining in real time the frequency characteristics (amplitude, frequency, and etc.) of mechanical constructions subjected to dynamic loads is presented. This method is based on the analysis of the behavior of the intensity of a single speckle. The optical scheme in which a simultaneous registration of a standard digital speckle interferogram on the CCDmatrix and the behavior of the intensity distribution in a single speckle with using high-speed point photodetector is presented, that allows to simultaneously determine the shape and amplitude of the resonant vibrations of the mechanical structures in realtime. The results of experimental researches are presented.

The field of speckle metrology has seen a surge in development in the past 10 years owing to advancements in digital cameras and computing power. For instance, a variety of digital speckle correlation (DSC) processes can now be performed in almost real time and therefore speckle techniques has found applications in nondestructive testing (NDT), biology, and medicine. New techniques in terms of optical arrangements and in extracting phase data have been introduced for measuring out‐of‐plane and in‐plane motions in digital speckle interferometry (DSPI) and digital speckle shear interferometry (DSSPI). DSC, DSPI, and DSSPI have also been combined to extend the range of measurements. In addition, quantitative analysis in speckle interferometry has seen a plethora of new software developments for conducting real‐time, accurate, complicated, fast, and repeatable measurements with ease. In addition, different methods to process speckle fringes have made analysis equivalent to that of classical interferometry, yet can be applied to all types of real‐world specimen.
