1. A multi-view diagnostic system, comprising:
an OCT engine;
a plurality of optical elements defining a plurality of beam paths between the OCT engine and an ophthalmic target, each beam path corresponding to a different viewing angle of the ophthalmic target;
a scanner configured to direct OCT imaging beams generated by the OCT engine toward the ophthalmic target along each respective beam path, direct first OCT imaging beams toward the ophthalmic target along a first beam path, wherein the first beam path corresponds to one of an optical axis and a visual axis of the ophthalmic target, and direct second OCT imaging beams toward the ophthalmic target along a second beam path defined by a set of static mirrors, wherein the second beam path intersects the first beam path within the ophthalmic target at an acute angle;
an illumination source configured to emit the illumination light, the illumination source comprising a plurality of illumination point sources arranged in one or more concentric patterns around an aperture that allows the OCT imaging beams or other light to pass through to or from the OCT engine;
a beam splitter optically aligned with the OCT engine and a camera optically aligned with the beam splitter, the camera configured to receive illumination light reflected by the ophthalmic target along each respective beam path; and
a processor and instructions stored in a memory, the instructions executable by the processor to:
determine a characteristic of the ophthalmic target based on OCT light reflected by the ophthalmic target along each respective beam path and detected by the OCT engine;
determine an optical intraocular lens (IOL) profile based on the ray tracing analysis and the detected OCT light, wherein the IOL profile includes a power, a shape, or a position of the IOL within the ophthalmic target; and
determine a characteristic of a cornea of the ophthalmic target based on the illumination light reflected by the ophthalmic target along each respective beam path.
