A pair of wedge prisms can be used to scan a laser beam over a specified angular range with a high resolution. The structural parameters of dual prisms directly influence the optical path and generate a tracking trajectory difference. For a remote target, the influences can be ignored, but for a near field target, the opposite is the case. The paper makes a comparison of rotating dual-prism scanner used in near and far field, as well as a forward solution and a reverse one of a laser beam through the rotating dual-prism system. The conclusion is valuable for a rotating dual-prism scanner to perform the optical tracking and targeting direction.
