Method and apparatus for measuring retinal blood flow |
摘要 |
Blood flow in retinal blood vessels is measured by directing laser radiation along an optical path into the eye and onto a blood vessel. Laser radiation reflected off moving blood corpuscles is directed back along the optical path and into a detector. This reflected laser radiation is mixed with a proportion of the original laser signal to determine the doppler shift produced by the moving blood corpuscles and hence blood velocity.
