The present invention provides a drive system for an optical light modulation system employing multiple light modulation element pairs (205, 215, 206, 216). The each pair is driven by a single motor (209, 219) which drives one axle (228) around which one element (205) of the first pair (205, 215) rotates while the other element (215) of the first pair (205, 215) free floats and rotates about a second axle (228). While the second axle (228) drives the rotation of the first element (216) of the second pair (206, 216) and the first axle (228) provides a rotation pivot for the second element (206) of the second pair (206, 216). Thus the two pairs share the two axles (228) providing a more compact drive system that can be used more flexibly in an optical train of an automated multiparameter lighting system. |
