Abstract

A simple, polygon-type flying spot scanner with high light throughput, well controlled spot size and good linearity is described. This compact underfilled, double pass optical system, with axial input provides a large scan angle with few optical elements and thus lends itself to a cost-effective design. Since the included scan angle is symmetrical with respect to the optical axis of all active components, a high degree of spot energy uniformity can be achieved. In addition, the spot size can be easily changed to accommodate a wide range of scan line densities. Several successful applications have proven that the system works equally well with gas or solid state lasers, and it can be applied both for raster input and output scanning, including color printing.
