Modeling the Method of Laser Doppler Speckle-Velocimetry for Flat Objects with Retroreflective Surface


Gregory Dolya, Olena Lytvynova

Abstract


The method of laser speckle-velocimetry based on the Doppler effect is considered. To increase the received signal power from a moving object, it is suggested to use a retro reflective sheeting in the form of a set of microscopic glass beads. A mathematical model of the proposed method is described. Physical simulation was carried out. The dependence of the power of the received signal on the frequency was obtained. The cases, when the values of the angles of incidence laser beam and the velocity of a moving object vary, were considered.
