Laser Doppler method of speed measurement in wide dynamic range

The paper presents new method for measuring flow velocity by sensing the mobile flow by two laser beams of different frequencies. The method of measurement enables creating of laser Doppler velocity meter (LDVM) to measure velocities as small and hypersonic.
