1. A system for retinal imaging comprising:
optical elements comprising an objective lens, the optical elements being configured to:
focus patterns of illumination on or near a pupil of an eye and illuminate a retina, relay and image the pupil onto a baffle-and-illumination module, and focus a plurality of imaging rays arriving from the retina through the pupil to allow at least one reimaging corrective optical module to image the retina onto at least one image sensor;
the baffle-and-illumination module comprising one or more baffles and one or more illumination sub-modules, wherein each of the one or more illumination sub-modules comprises one or more light sources of a plurality of spectrum ranges and one or more waveguides configured to generate emissions of shapes and sizes to produce the patterns of illumination, wherein at least one of the one or more baffles is an opaque structure comprising an aperture, and wherein the at least one of the one or more baffles is configured to block light other than a reflected light from the retina;
the at least one reimaging corrective optical module comprising one or more optical components configured to correct aberrations, adjust diopter, adjust astigmatism, adjust focus, or change image magnification of a retinal image before the retinal image reaches the at least one image sensor and the at least one image sensor; and
a control unit configured to dynamically adjust one or more imaging parameters in real-time, including focus and light intensity, wherein the adjustments are made during the imaging process to optimize image quality based on the anatomical characteristics of the patient's eye.
