Beam positioning and pointing
Abstract:
A beam pointing and positioning system includes a first lens, movable in a first plane perpendicular to a nominal optical axis, which receives and positions a light beam. The system also includes a second lens, movable in a second plane perpendicular to the nominal optical axis, which receives and points the positioned light beam. The system is thereby capable of directing the light beam to a desired location at a desired angle. The system may also include a beam splitter that receives, transmits, and reflects the pointed light beam, one or more sensors that receive the reflected light beam, and a controller coupled to the sensor(s) and first and second lenses. The controller may control the positioning of the first and second lenses based on beam position and pointing data and/or signals received from the sensor(s). A method of positioning and pointing a light beam is also presented.
