Compact video-rate optical scanner (CVROS) for finite conjugate applications

The CVROS scanner, a new approach to high speed serial optical scanning employing a scan disc, has been successfully developed for thermal imaging. Its high speed, high scan efficiency, wide field, and mirror optics suggest applicability to broad band visible scanners and projectors as well as laser and UV printers. This paper reviews the CVROS concept and presents the configuration adaptations required for finite conjugate applications. Design and performance characteristics are given for several configurations as well as key alignment and manufacturing requirements.
