WebMar 7, 2006 · The reason they give for this association between slit pupils and multi-focal optics is that a slit samples from the whole diameter of the lens, even in daylight when the pupil is constricted, whereas a constricted circular pupil will only sample the central zone of the lens (Figure 1 B–D). Thus the multi-focal chromatic correction is ... WebNerve problems can affect the nerves of the muscles surrounding the eyeball and those that control the dilation and contraction of the pupil. Such problems can result in symptoms such as double vision, nystagmus, oscillopsia and disorders of the pupils, such as anisocoria. The doctor is likely to evaluate a person with these problems carefully ...
WebThe pupils of an optical system are images of the aperture stop; typically, machine vision lenses have embedded aperture stops, with individual lens components surrounding it on either side. The entrance pupil is the image of the aperture stop into object space, and the exit pupil is the image of the aperture stop into image space.
