Patent ID: 7256834

Claim:
An apparatus for panning and tilting an optical input to an objective of a stationary camera; and the apparatus comprising: a panning mirror rotationally coupled to the camera for bending the optical input to align with an optical axis of the objective and the optical input and the optical axis defining a plane, and a rotation of the panning mirror panning the optical input to the objective of the camera about the optical axis; a tilting mirror radially displaced from the panning mirror about the optical axis, and rotationally coupled to the camera for rotation concentric with the panning mirror about the optical axis, and the tilting mirror optically coupled with the panning mirror and the titling mirror configured to tilt the optical input in selectable amounts about an axis substantially perpendicular to the plane; and a planetary linkage coupling the panning mirror and the titling mirror, and including: a mirror wheel rotatable about the optical axis, and the panning mirror affixed to the mirror wheel and the titling mirror tiltably affixed to the mirror wheel both for rotation about the optical axis; a guide wheel rotatable about the optical axis; and a planetary member mechanically coupled to both the guide wheel together with the mirror wheel to convert a relative rotation there between into a rotation of the planetary member and the planetary member further coupled to the tilt mirror to convert rotation of the planetary member into titling of the tilt mirror.
