Hi all,

How do people use an image formed on a curved image plane, like, say,
the image of a patch of night sky containing starts taken by a Schmidt
camera?

My question is that suppose you want to print the sky image in a book,
or show it on a computer screen, since these are flat media, will the
"mapping" between a curved surface and a flat one cause image
distortion?

Thanks

In general one does not actually have a curved (spherical) image plane
because (except for fiber faceplates) detectors are not curved.  There
will usually be a field flatener in front of the image plane.

Actually the image plane (and the recording media, such as
photographic film) is curved for a Schmidt sky survey camera....both
the mirror and the image plane are spherical.

Traditionally that's true.
