An optical image stabilizer is used to compensate for an unwanted movement of an imaging system, such as a camera. The camera has a folded optics system using a triangular prism to fold the optical axis. Two actuators are used to rotate the prism around two axes in order to compensate for the yaw motion and pitch motion of the camera. The prism can be mounted on a gimballed system or joint and two actuators are operatively connected to the gimballed system in order to rotate the prism. Alternatively, the folded optics system uses a mirror to fold the optical axis, and two motors are used to rotate the prism. |
