focal plane shutter theory (Slit Scan Shutters)

Murray had said "I would like to understand (actually, analyze) the
operation of a focal plane shutter, for the purpose of building one for
sheet film. I want to get a grasp on calculating exposure duration as a
function of slit width and linear speed, I guess (or direction to what I
should be thinking about)."

All shall be revealed, grasshopper...

Head on over to the incredible Andrew Davidhazy site from RIT:

And note the Slit Scan Photography article here:
http://www.rit.edu/~andpph/text-slit-scan.html
(as well as many more on Slit Scan)

A big ol' slab of juicy math awaits:

IMHO, this is one of the greatest sources of creative energy I have ever
found on the web when it comes to innovative camera designs and very, very
exciting results. FYI, Andrew Davidhazy is from the School of Photographic
Arts and Sciences, Imaging and Photographic Technology, Rochester Institute
of Technology. The guy is truly amazing. I may quit my job and go back to
school there, but for the wife, son, mortgage, etc... And, FYI, he is
