Abstract
A rotary motion controller controlling the motion of a mirror in a projection system is described having a mounting element coupled to a support member. A two-axis coupling is provided with at least two input shafts coupled to two drive mechanisms. A channeled portion is provided in a second of the two input shafts through which the support member extends there through and is guided thereby and where the at least one support member is coupled to the first input shafts via an input coupling coupled to and driving the support member and a control input controlling the position of the at least two input shafts. A method of controlling a mirror in an underwater projection system is also provided along with a method of operating a controller for an underwater projection system and a further embodiment for providing movement of a mirror in an underwater projector.
