Mechanical engineering

In this article it is described the advantages of the laser contactless vibration diagnostics of machines and constructions condition allowing early defect detection due to ability of getting access to every point located on the machine and construction casing outside surface and vibration measurement frequency range broadening. Examples concerning laser diagnostics of aircraft engine parts in test bed conditions with the utilization of spectral and statistical processing methods are shown in this article.
