Variants of these algorithms allow for simultaneous reconstruction of the pupil function of an optical system, allowing for the correction of the aberrations...

of the pupil between 1.5 mm and 8 mm, via the optic and oculomotor cranial nerve. A constriction response (miosis), is the narrowing of the pupil, which...

the exit pupil is a virtual aperture in an optical system. Only rays which pass through this virtual aperture can exit the system. The exit pupil is the...

constriction of the pupil. The opposite condition, mydriasis, is the dilation of the pupil. Anisocoria is the condition of one pupil being more dilated...

which are nowadays called nystagmus. It is particularly noticeable when pupil function is tested with a light, but is independent of eye movements or changes...

the lens, the MTF is the autocorrelation of the pupil function, so it accounts for the finite pupil extent and the lens aberrations. The sensor MTF is...
