Laser scanning system using a rotationally asymmetric aspheric surface.
In recent laser beam printers, higher resolution and a more compact system design are always desired. In this study, a rotationally asymmetric aspheric surface is introduced to achieve these purposes. This surface can completely eliminate field curvature aberration caused by the oblique incidence of the laser beam to the scanning optics, achieving high resolution over a wide scanning range.
