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, and
damping means coupled between the imaging unit and the movable reference structure.
