Abstract
The paper presents an analysis of the optical technique for low frequency biovibrations sensing. The suggested method makes use of dynamics of speckles induced by focused coherent fields diffraction from vibrating surface. Computer simulation of strongly focused coherent beams scattering from a vibrating skin surface has been carried out for cases of in- plane and angular vibrations. The dependence of output characteristics of the developed speckle-using vibration sensor on vibration type and relations between the amplitude of surface oscillations, illuminating beam waist size and the scale of the surface inhomogeneities has been analyzed. Results of biovibration monitoring using the proposed technique are presented.
