Apparatus for controlling the position and direction of a laser beam

摘要: An apparatus for maintaining an electromagnetic beam, namely a laser aimed at particular point in space and aligned with unique propagation path. The includes one or more adjustable beam steerers located the path, first second spaced apart position detectors arranged steerer(s) are preferably along least two orthogonal axes of rotation controlling direction beam. Error signals from sensors fed into steerer controller connected to electro-mechanically adjusting steerer. method invention involves fixing path on angularly steering surface so that different space, such as target, can be controlled by angular orientation
