ABSTRACT
This chapter provides the background knowledge that will help develop an insight and intuition for optical designs in general and scanning systems in particular. Design issues and considerations for holographic scanning systems are discussed in detail. The chapter also provides a familiarity and some rules of thumb as guidelines for the design of scan lenses. The multiconfiguration technique of design is discussed in more detail. The key to exploiting the multiconfiguration design method is to include the rotation axis when modeling the polygon. A brief overview of such a model begins with the definition of the expanded laser beam, followed by a first fold mirror, the defined polygon with its rotation axis, and finally the scan lens. The lenses were selected to show what appears to be the trend in development. Selecting real glasses for the final design iterations results in the design and performance as illustrated in the chapter, with no noticeable change in performance.
