Described is a compact focal plane shutter system adapted for large-format
exposure shutters. The focal plane shutter includes at least one
multi-segmented screen having multiple rigid blades. Each blade can be
moved at a different velocity. By using multiple blades, the rotational
inertia about a drive axis can be reduced compared to a conventional
single screen shutter system, thus a greater acceleration can be achieved
with the same amount of torque about the drive axis. Using smaller blades
allows for greater acceleration, resulting in faster shutter speeds to
support a wider range of applications. Additionally, the overlap between
blades of a multi-segmented screen in an open position is greater than
the overlap of the blades in a closed position, providing a compact
system. A drive mechanism linearly translates the blades of the
multi-segmented screen between the open and closed positions.
