1. A projection system for forming an image, said projection system for minimizing the effects of vibration on the appearance of the image, comprising:
- a) a movable reference structure;
b) an imaging unit mounted to the movable reference structure and configured to supply a light beam carrying an image; and
c) a mount structure mounting the imaging unit to the movable reference structure, the mount structure being at least partially single degree of freedom of motion (SDFM) compliant, the mount structure comprising;
a coupling plate,a pair of SDFM units connected in series with the coupling plate and disposed between the imaging unit and the movable reference structure, anddamping means coupled between the imaging unit and the movable reference structure.

Abstract
A projection system includes a vibration controlling structure. The projection system includes an imaging unit mounted to a movable platform via a partially compliant mount structure, such that the imaging unit is partially isolated from the platform while projecting an image which is stable with respect to the platform. The imaging unit and partially compliant mounting structures are constructed and arranged to damp vibrational forces on the imaging unit.

17. A projection system for forming an image, said projection system for minimizing the effects of vibration on the appearance of the image, comprising:
-
a) a movable reference structure; b) an imaging unit mounted to the movable reference structure and configured to generate an image having a virtual origin point at which the image appears to an observer; and c) a mount structure mounting the imaging unit to the movable reference structure, the mount structure being at least partially compliant, the mount structure comprising; a plurality of guides coupled to the movable reference structure, each guide forming an arc of a circle centered at the virtual origin point, a bearing slidingly mounted on each guide and coupled to the imaging unit, and damping means coupled between the imaging unit and the movable reference structure.
