EYE-IMAGING APPARATUS AND METHOD EMPLOYING SEQUENTIAL FLASHING OF ILLUMINATION LIGHT IN SYNCHRONIZATION WITH THE OPERATION OF AN IMAGE SENSOR

Abstract:

An eye-imaging apparatus and system is described including circular fiber array ends arranged at skewed angles relative to the optical axis of the imaging path, a light intensity distribution converter along the illumination path to convert a bell-shaped distribution into a top-hat distribution, an image sensor, and high frequency response light source(s) operating in flash illumination mode in synchronization with the image sensor. As a result, unnecessary exposure of illumination light to a patient eye is minimized while the illumination light can span a wide enough coverage range with desired intensity and spectral distribution to cover the desired angular field of view and spectral range on a retina.
