ABSTRACT:
A shutter is rotatably mounted within a housing for opening and closing a shutter aperture formed in the housing. The shutter is coupled to a drive unit for unidirectionally rotating the shutter with the same velocity profile to open and close the shutter aperture during each exposure period. This drive unit includes a source of position and velocity data and a feedback loop configurable for either position or velocity control of the shutter as determined by a control command.
