Abstract
The present invention provides a drive system for an optical light modulation system employing multiple light modulation element pairs. The each pair is driven by a single motor which drives one axis around which one element of the first pair rotates while the other element of the first pair free floats and rotates about a second axis. While the second axis drives the rotation of the first element of the second pair and the first axis provides a rotation pivot for the second element of the second pair. Thus the two pairs share the two axises providing a more compact drive system that can be used more flexibly in an optical train of an automated multiparameter lighting system.
