The laser Doppler velocimeter was operated in the dual-beam near full backscatter mode and is composed of a 600 mW argon-Ion laser, a diffraction-grating unit to divide the light beam into two equal intensity beams and to provide frequency shift, and collimating and focusing lenses to form the control volume.
