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 diffiacon from vibrang surface.Computer simulation of strongly focused coherent beams scattering from a vibrating skin surface has been carried out for cases ofin-plane and angular vibrations. The dependence of output characteristics of the developed speckle-using vibration sensor on vibration type and relations between the am… Show more
