Abstract

A Bragg-angle holographic scanner (where both the incident beam and diffracted beam make equal angles with the spinner at mid scan) is described. Exact beam trajectory equations derived by vector analysis are presented for both a general holographic scanner and for the Bragg-angle scanner. Parametric data is presented for an example scanner and from this family of possible solutions conditions for minimum spinner diameter are determined. By adding output prisms between the spinner arid f-theta lens an additional significant reduction in spinner size is achieved. Other benefits of output prisms are described. 1.
