<title>Principles of the ideal scanner model: an analytical theory of the banana mirror system</title>

Abstract

The banana mirror system is an alternative approach for the design of telecentric laser scanners with a large scan format instead of using an f-(theta) scan lens. We developed an analytical model describing the ideal banana scanner configuration, that consists of a converging beam which is deflected as a pure cone (generating a primary scan circle) and a combination of a hyperbolic and a parabolic cylindrical mirror. this model is called the Ideal Scanner Model (ISM). We will introduce the concept of conical deflection and present the basic features of the ISM theory.
