Re: *really* high speed photography question

[Andrew Davidhazy <andpph@xxxxxxx>]

I believe (not positive) that this camera used a Pockels Cell (solid Kerr cell) 
shuttering mechanism. All electromagnetic. Angle of polarization of light 
passing through a "glass" block was briefly rotated by an electromagnet so that 
it would match that of a second polarizer which was oriented so its plane of 
polarization was crossed to that of the first or front polarizer. So, under 
normal conditions transmission of the system as very low. When angles were 
aligned transmission was better ... but still pretty low! But when you have a 
lot of light to start with (nuclear blast) low transmission of an optical system 
is generally not a problem.

Now, note that this is off the top of my head and there seems to be less and 
less "stuff" there.
