Abstract
An eye-imaging apparatus and system is described including arrayed optical fibers having a high numerical aperture and circular fiber array ends arranged at skewed angles relative to the optical axis of the imaging path. Circular fiber array ends are arranged to emit the illumination light into an eye at a skewed angle and a light intensity distribution converter along the illumination path to convert a bell-shaped distribution into a top-hat distribution. As a result, illumination uniformity on the retina of the eye is improved.
