Abstract
An economical refracting type laser beam scanning device, exhibiting a minimum across-scan error without corrective measures, is described. The main structural assembly of the device consists of a rotating prism, a fixed spherical lens, and a fixed convex spherical auxiliary reflector (SAR). Trigonometric equations are developed to determine the radius of curvature of the SAR and the size of the exit pupil. Resolution analyses are presented for a specific set of design parameters.
