Eichhorn JL. In order to take measurements of electrical and mechanical characteristics on red blood cells in motion in a hydrodynamic or electric field, a micro laser doppler anemometry apparatus was developed.

What is laser doppler velocimetry ? This is a technique to determine the local velocity of a flow by fine particles in the air with high temporal resolution and in a non-intrusive way. The particles within the flow pass through interference fringes created by interaction between two coherent laser beams.

Pulsatile waveforms and physiologic flow divisions were incorporated. Disturbance levels and shear stresses were computed from ensemble averages of the velocity waveform measurements. LASER DOPPLER ANEMOMETRY Dennis A. Johnson NASA Ames Research Center Moffett Field, CA 94035, U.S.A 1. INTRODUCTION Laser Doppler anemometry (LOA) in compressible flows offers the advantages of unambiguous signal interpretation (the laser Doppler anemometer senses VelOClty Only) and nonlntruslveness. Abstract: The Laser Doppler anemometry was employed to determine quantitatively the liquid velocity induced by the successive rising of single bubble in non-Newtonian carboxymethylcellulose (CMC) aqueous solutions under various experimental conditions of mass concentration solutions, measures heights and gas flow rate. Laser Doppler Anemometry (LDA) is the ideal measurement technique for the non-intrusive investigation of velo-city and turbulence in gas or liquid flows. The applications described in this brochure demonstrate the wide relevance of LDA across the spectrum of scientific and industrial research.
