Eye imaging apparatus with a wide field of view and related methods

An eye imaging apparatus comprising:

• a housing;
• a light source disposed inside the housing comprising a plurality of light emitting elements configured to illuminate different portions of an eye time-sequentially;
• an optical imaging system inside the housing comprising:
• an optical window at a front end of the housing;
• an imaging lens positioned behind the optical window and optically aligned with the optical window;
• an image sensor configured to receive a plurality of images of the eye with a same field of view through the optical imaging system while each portion of the eye is illuminated time-sequentially.

A compact eye imaging apparatus comprising:

• a housing;
• a light source disposed inside the housing to illuminate an eye;
• an optical imaging system comprising:
• an optical window with a radius of curvature closely matching a curvature of a cornea of the eye at a front end of the housing,
• an imaging lens optically aligned with the optical window, said imaging lens positioned behind and separated from the optical window by a gap,
• at least first and second relay lenses, and
• at least one miniature lens with a clear aperture size less than 5 mm configured to form the image of the eye based on light received from the at least first and second relay lenses;
• and
• a miniature image sensor with a format less than 1/1.5 inch configured to receive the image of the eye formed by the at least one miniature lens.
