Study on the Stray Light Suppression of Fundus Camera

Fundus camera is a system that is a kind of observation and records the images of the retina of the eye. Through these retinal images, it can diagnosis Systemic diseases early, but Stray light will make the images blur and contrast reduction, reduce the ratio of Signal to noise of the images, affect the fundus camera imaging quality seriously, we must eliminate it. In this paper, aiming at the fundus camera stray light sources that gives the corresponding stray light suppression measures, for the fundus camera’s further developments provide a reference, prospecting the future technology development of eliminating stray light.
