Abstract
The paper describes a mobile laser system based on a noise-proof digital speckle pattern interferometer for studying the coupled vibrations of the bladed wheels during engine development stage. The mechanical properties influence of the optical scheme elements of the speckle interferometer when recording information without vibration isolation is studied. It is noted an improvement in the quality of the obtained speckle interferograms with an increase in the construction rigidity of the diffusely scattering element of the speckle pattern interferometer.
