Paper Abstract

The paper describes the development of laser Doppler anemometer system for the determination of in vivo retinal blood velocity and to provide information relevant to the flow of blood in the human retina. Due to the large dimension of the laser Doppler measurements probe volume relative to a typical retinal blood vessel, a special correction scheme has to be applied. In the present work the ratio of probe volume length to tube diameter was about 2.0, which unless compensated for could result in inaccuracies larger than 20% when attempting to recover the flow rate within the vessel. In order to investigate the magnitude of the phenomena, we devised a two phase flow (liquid-solid) experimental system. The program was designed to verify the ability of the maximum velocity (at the tube center) to represent the average cross sectional velocity.
