ABSTRACT:
A device for accurately positioning an optical system element uses an array of electromagnets to alter fluid pressure distribution in a mass of ferromagnetic fluid. The pressure redistribution causes movement of an optical system element positioned adjacent to the ferromagnetic fluid. The invention is concerned with particular arrangements of fluid and energizing electromagnets to ensure combined rectilinear and angular movement of the optical system elements. The device has neither the complexity nor the delicacy of known structures used for moving optical system elements.
