Measurement of Dynamic Characteristics of Structures by the Speckle Interferometry on Single Speckle
- In this article the results associated with the use of speckle interferometry on a single speckle to determine the dynamic characteristics of mechanical constructions are presented. The optical scheme of the speckle interferometer on a single speckle is proposed, which makes it possible to simultaneously record the form and amplitude of the resonant vibrations of mechanical constructions. Theoretical and experimental results demonstrating the behavior of the output signals from the speckle interferometer on a single speckle in the study of the resonant vibrations are presented. The resonance method for measuring the logarithmic decrement of vibrations and other dynamic characteristics of a mechanical constructions using speckle interferometry on a single speckle is proposed.
