摘要： Embodiments of the present invention relate to a family of image-rotation prisms. Each image-rotation prism has the property that as an image-rotation prism is rotated, an image passing through the image-rotation prism rotates at twice the angular rate of the image-rotation prism. Embodiments of the present invention include optical systems that can be used for board-to-board communications and employ the image-rotation prisms to compensate for arbitrary axial rotations and misalignment of optical signals and can be used to direct optical signals output from transmitters on one board to particular detectors of a detector arrangement located on an adjacent board.

The rectifier diode is used for commutating current maintained by the electromotive force generating at both terminals of the inductor. The inductor is used for storing energy according to the current flowing from the input voltage via the transistor. The output capacitor is used for smoothing a voltage of the inductor.
