Electromagnetic beam or image stabilization system
First Claim
1. An electromagnetic beam stabilization device comprisinga gimbal having at least two axes of rotation, a first axis of rotation and a second axis of rotation substantially perpendicular to said first axis of rotation, said gimbal having a center of rotation corresponding to the point of intersection between said first axis of rotation and said second axis of rotation and any additional axes of rotation;
- at least one parabolic mirror fixed within said gimbal, said parabolic mirror having a focal point that substantially coincides with said center of rotation; and
at least one electromagnetic beam emitter positioned so that a beam maintains focus on a point substantially at said center of rotation and thereafter strikes said parabolic mirror.

Abstract
An electromagnetic beam stabilization device comprises a parabolic mirror fixed within a gimbal so that the focal point of the parabolic mirror coincides with the gimbal'"'"'s center of rotation, and an electromagnetic beam emitter, such as a laser, positioned so that a beam maintains focus on a point substantially at the center of rotation and thereafter strikes the parabolic mirror. The beam'"'"'s focal point may be repositioned using repositioning optics like a flat mirror. An image stabilization device comprises a parabolic mirror fixed within a gimbal so that the gimbal'"'"'s center of rotation coincides with the focal point of the parabolic mirror, and an image sensor having an image plane that coincides with the focal plane of the parabolic mirror. The parabolic mirror'"'"'s focal plane may be reimaged using reimaging optics like an elliptical mirror. The laser stabilization and image stabilization features may be combined in a single device.
