Abstract:
A pan/tilt apparatus for a camera includes a base, a stage mounted on the base to rotate around a vertical pan axis, an optical apparatus mounted on the stage, a pan actuating mechanism, and a tilt actuating mechanism. The optical apparatus includes a frame that supports a magnetic structure and a mirror such that they are pivotable around a horizontal tilt axis. The mirror receives an image directed along an incident axis, and redirects the image along the pan axis, e.g., to a camera that is disposed on or below the base. The pan actuating mechanism engages and rotates the stage into a desired pan direction. The tilt actuating mechanism modulates (alters) a magnetic field applied to the mirror/magnetic structure by, for example, moving a permanent magnet that is mounted on the base.
