ABSTRACT:
A vibration stabilized image projection system includes a viewing screen supported on a vibratory platform, an image projector supported off the platform in a relatively vibration-free environment for projecting an image toward the screen, and an image stabilizing lens interposed between the projector and screeen for providing an optical link between them. The stabilizing lens is supported on the platform for undergoing vibratory movement therewith in X, Y and/or Z planes and relative to the projector. The lens focuses the image at a stationary position on the screen as the stabilizing lens, screen and platform undergo vibratory movement relative to the projector.
