ABSTRACT:
An optical apparatus for selectively directing a line of sight between a residence location and locations within a substantially hemispherical field of regard. The apparatus includes a stator which supports a first stage for rotation about a first axis of rotation. A second stage is supported by the first stage for at least partial rotation about a second axis of rotation. The first stage and the second stage include respective mirrors which direct the line of sight between the residence location and the locations in the field of regard. The first stage and the second stage are each operatively rotated by one or more foundation-based drive motors or the like. A drive train arrangement is preferably utilized to transfer motive power from the stationary drive motor to the second stage.
