focal plane shutter theory

This may be off topic, but the breadth of knowledge within this group may
provide me an answer (off list , if necessary).

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).

Thanks
