which is the geometric center of the cornea, and the line that connects this central point to the retina is the optical axis. The pupil center is not often perfectly aligned with the optical ...

“The center of the pupil is quite variable. It can be located on the visual axis, on the optical axis or, most of the time, about halfway between the two,” Dr. Holladay said. “For that ...

Typically made of a highly reflective material such as aluminum, a standard parabolic mirror will center on the vertex of the paraboloid. This is the point where the curvature is greatest, and where ...

Based on coaxial and off-axis imaging characteristics, recommendations for optical sectioning methods in different applications have been provided according to the geometry of biological samples ...
