Abstract

Noncontact measurement of mechanical vibrations is one of the actual problems in engineering. One of the methods widely used is spectrum analysis of Doppler shifts of coherent light reflected from a vibrating surface. Statistical properties of radiation scattered from an out-of-plane vibrating object have been studied. We are examining the possibility of deriving vibration parameters from statistical parameters of the dynamic speckle pattern formed by reflection of a coherent beam from the in-plane vibrating rough object.
