Optical Device for Measuring Small Displacements of Control Objects Surfaces with Protection from External Mechanical Loading

Abstract

The paper describes high-precision contactless optical devices for measuring small linear and angular displacements of the surfaces of control objects based on modern laser technologies and new methods of optical interferometry. A new scientific-based technical solution has been proposed, which allows one to provide continuous protection against the influence of external mechanical loading in the measurement process. The proposed technical solutions are successfully used to solve actual scientific and industrial problems and can also be successfully used to control the quality of structural materials and diagnostics of the state of goods under operating conditions in mechanical engineering, shipbuilding, aircraft construction, etc.
