I need to use an artificial pupil for a luminance increment detection
expt. I haven't used one before. Basically an artificial pupil is just
a hole in a piece of sheet metal (say a 2mm hole in a piece of metal
1mm thick, spray paint it all black). My question: the pupil needs to be
close to the cornea, so does that mean no spectacles? The pupil has to
be brushing the eyelashes? I guess refractive correction can be placed
as follows:
cornea-pupil-corrective lens--------------------------light source.
Corrective lens(es) between pupil and light source.
(That would only work "in theory" in my case, because I don't think it is
worth the expense of buying a set of lenses or the trouble to set up the
extra apparatus for holding them. So I guess I would just use emmetropes)
Thanks for any help.
