ABSTRACT:
Apparatus for stabilizing the image of an electro-optical sensor system. The stabilizing apparatus includes a mounting structure subjected to various rotational and translational vibrations of various sorts. The mounting structure supports a platform on which the electro-optical system is mounted. The platform system comprises a platform structure isolated from the mounting structure either as a passive system, that is, one which supports the platform through a soft isolator, or as an active system, that is, one in which an actuator is mounted in parallel with the isolator in series with a bearing or flexure or other rotational decoupling. The reflective apparatus of the electro-optical system is driven by an actuator mounted on the mounting structure, i.e., in parallel with the series combination of the reflector and platform, in response to tracking signals derived from line of sight sensors mounted on the platform. This allows the shunting of reaction torques directly to the mounting structure, thereby eliminating the excitation of platform resonances.
