CCD detection and Modulation: Can it be done?

You could think about using a frame transfer device with
separate parallel clocks to the upper and lower halves of 
the CCD.  The readout section half would be screened with
some sort of mask.  If you use a limited number of rows
and employ creative clocking, you could expose during limited
row readout, do a fast parallel shift then expose again during
the serial readout of n rows.  With the proper modulo n, the 
mask half of the ccd would be in a "movie" mode with data
(signal+noise alternate with noise) separated by a dead space
of n rows.  This dead space n rows would simply be annihilated
after/during the fast parallel shift. Tough to visualize this
operation without a drawing/diagram and clocking sequence.

You can get the time resolution you talk about with good low
noise with any reasonable CCD.
