Abstract
The invention is a method and apparatus for deflecting a beam using multiple beam scanning galvanometers. One or more embodiments of the invention comprise a system for deflecting an energy beam comprising a first reflective surface for directing an incident beam, a first galvanometer coupled to the first reflective surface for rotating the first reflective surface about a first axis, a second reflective surface for directing the incident beam after directed by the first reflective surface, and a second galvanometer coupled to the second reflective surface for rotating the second reflective surface about a second axis, the second galvanometer positioned remote from the first galvanometer. In one or more embodiments, the system is a part of a laser film recorder. In such an embodiment, the incident beam comprises combined red, green and blue laser beams. The incident beam is directed by the second reflective surface at a film surface.
