Abstract
A scanning system for linearized application of an energy beam along at least one of a plurality of predetermined axes. Chopper means intercept the energy beam for alternately reflecting and passing the energy beam providing successive reflective and passed beams respectively therefrom. First and second scanning means receive the reflected and passed beams respectively. The first and second scanning means synchronously direct the reflected and passed beams along at least one of the predetermined axes.
Claims17
A scanning system for linearized application of an energy beam along at least one of a plurality of predetermined axes comprising:
- chopper means intercepting said energy beam for alternately reflecting and passing said energy beam and providing successive reflected and passed beams respectively therefrom;
- and
- first and second scanning means for receiving said reflected and passed beams respectively, said first and second scanning means synchronously directing said reflected and passed beams along at least one of said predetermined axes.
A method for linearized scanning of a continuous energy beam along at least one of a plurality of predetermined axes comprising the steps of:
- providing a source of said energy beam;
- interrupting said energy beam by means of a chopper;
- reflecting said energy beam by means of said chopper producing a reflected beam;
- alternately passing said energy beam by means of said chopper providing a passed beam;
- receiving said reflected and passed beams by means of respective first and second scanning means;
- and synchronously directing said reflected and passed beams along at least one of said predetermined axes.
