Development and Application of Mobile Digital Speckle Interferometer for Vibrometer Model Sample Honeycomb

Abstract

The problems of the development of mobile digital speckle interferometer with a cw laser to obtain the vibration characteristics of the full-size structures in factory laboratories. Given the results of the use of the mobile testing interferometer for the study of vibration characteristics of model samples of honeycomb panels, different way to connect mobile plate frame with power-trim. Considering the cellular plate as a system with distributed parameters provides a method to determine its natural frequencies and mode shapes by acoustic excitation. The experimental results are compared with those of serial laser Doppler vibrometers.
