Paper Abstract

The double dove prism is a common method used to achieve large scan angles with a straight line configuration. The basic concept uses two cemented dove prisms rotating at one half the desired scan angle. In most cases, this double dove prism is used behind a flat window. This paper investigates the design considerations required to use the double dove scanner behind an optical element with power, in particular, a concentric dome. The limits to achievable resolution are explored, as well as methods to compensate for the aberrations introduced by the power element.
