Застосування лазерних допплерівських технологій для віброметрії

Abstract

A variety of uses for the Doppler effect, its application in practice and theory, are considered. Changing the frequency and, accordingly, the wavelength of the radiation are perceived by the observer (receiver) due to the movement of the radiation source relative to the observer. Basics of the self-mixing laser Doppler vibrometry are considered. This technique is used for miniaturization of the laser Doppler vibrometry systems
