Abstract
An improved prismatic polygonal reflector with increased aerodynamic properties and reduced scattering of reflected light is provided. The reflector may be used for scanning, and may include a first end, a second end, a plurality of side surfaces located circumferentially about a center axis of the reflector, and a plurality of intersections joining the plurality of side surfaces. Each of the plurality of intersections includes a curved or a flat portion and a pointed portion aligned circumferentially with other pointed portions on the plurality of intersections to provide a circumference around the reflector for light to reflect and form a scanning beam without light scattering. A system and method for scanning with the reflector is also provided.
