Abstract
The design of rotating mirror deflectors should be predicated on cost performance trade-offs. Precision, relatively costly rotating polygons are used for 100 MHz laser recorders but a less precision counterpart can be used in a very cost effective manner for laser supermarket POS scanning systems. Parameters of deflector design are discussed with respect to scanner configuration and how its choice affects cost and scanner accuracy. Limits of speed required, driving power, material selection, types of bearings and available motors are also discussed. Examples of a sophisticated precision air bearing scanner and a low cost simple rotating mirror deflector with a ball bearing motor are presented.
