Systems and apparatuses for three-dimensional eye imaging for screening, monitoring, and diagnosis of diseases

A system of retinal three-dimensional (3D) imaging, comprising:

• an image sensor within a light path;
• a reimaging corrective optics module within the light path, comprising multiple optical elements configured to correct aberrations, adjust diopter, adjust astigmatism, and adjust focus of a retinal image before the retinal image reaches the image sensor;
• an objective lens in the light path, configured to:
• focus a pattern of 3D structured light illumination from a 3D structured light illumination module onto or near an eye pupil plane;
• and
• relay and image the pupil of an eye onto an aperture of a baffle-and-illumination module;
• and
• a baffle-and-illumination module in the light path, located between the objective lens and the reimaging corrective optics module, the baffle-and-illumination module comprising:
• one or more baffles comprising an opaque structure with a hole aperture to block partial reflections of undesired light from the cornea and stray light other than the reflected light from the retina;
• and
• one or more illumination sub-systems configured to operate in a spectrum range including at least one of white light, red light, green light, blue light, or near infrared light.
