Optimal parameters for retinal illumination and imaging in fundus cameras.
A fundus camera is a complex optical system for imaging the retina of the eye. Designing a fundus camera requires the combination of an imaging system and an illumination system to share common optics. This combination of systems results in the need to find an optimal balance between imaging and illuminating the retina. We present a series of parameters and methods used to optimize the illumination system of a fundus camera while maintaining excellent image quality.
