Holographic-interferometry methods employed for vibration-strength testing of aviation-engine workpieces

The task of computing the vibroshifting fields of aviation engines and turbine blades by holographic-interferometry data is discussed. Interferometric optical and structural schemes of an automatized system of vibration investigation are presented. Mathematical tools for image-processing and the cor...

Description
Summary:The task of computing the vibroshifting fields of aviation engines and turbine blades by holographic-interferometry data is discussed. Interferometric optical and structural schemes of an automatized system of vibration investigation are presented. Mathematical tools for image-processing and the corresponding algorithms used for vibroshift-field computing are described. Results of experimental investigations are reported.
