A PUPIL COATING FOR QUASI-PERFECT IMAGE FORMATION

QC 351 A7 no. 21 / It is found that, despite the finite extent of any real pupil, an
absorption coating exists which, when applied to the pupil of an optical
system, results in nearly perfect formation of the coherent image. It is
suspected that this coating causes a significant loss of total illumination.
On the other hand, an "active" pupil (one for which there is a gain
in light flux) would allow the quasi-perfect imagery without any loss in
total illumination. When active pupils become a technological reality,
this will be a good use for one.
