Laser Doppler velocimetry was performed on retinal vessels of a cat using a linearly polarized He-Ne laser as the incident beam. The diameter of the vessels measured was <120 µm. Measurements show that if double transmission of the laser light through a given retinal vessel can be prevented, the Doppler shift power spectra have the shape theoretically expected from calculations based on a single scattering model and parabolic velocity profile of the red blood cells.
