Paper Abstract

The advances in the digital data processing and in design and manufacturing of high-performance single-facet scanning devices have made large scan-angle, high-speed/high-resolution digital imaging on cylindrical surfaces possible. Single facet deflectors operating at high speeds in open air tend to be noisy (70+ dBA at 30,000 rpm), collect contaminants (hence requiring frequent cleaning), and require high power to overcome the windage (hence high heat dissipation). For converging laser beam systems, flat and cylindrical window enclosures cannot be used as they induce astigmatism. A spherical window enclosure introduces power and spherical aberration. However, when a spherical window enclosure is used with a spherical lens before the deflector, power and spherical aberration can be eliminated.
