Paper Abstract

We have developed an all holographic line scanner for use in diode laser printers. The scanner consists of only a holographic disk and a holographic lens for laser scanning and focusing. No other optics such as a collimating lens and f- θ lens are necessary. The holographic disk performs high precision straight line scanning. The focusing function is achieved by the compound optical power of a holographic disk and lens. To make the disk more compact, while retaining a required scanning width and scanning beam, the increasing deviation from a straight line and scanning beam aberration need be overcome. In this paper, we devised the method to obtain the required phase transfer functions of the holograms and discussed the holographic recording method to fabricate the holograms.
