Abstract: A beam directing telescope for use in a directed energy weapons system that employs active telescope component alignment and that includes a primary mirror and a secondary mirror. The secondary mirror includes a first surface having a dichroic coating that reflects and directs a high energy laser beam to the primary mirror, reflects a portion of the reference beams and passes a portion of the reference beams that are focused by a second surface of the secondary mirror. A position sensing detector (PSD) is positioned relative to the secondary mirror such that the reference beams are focused as a spot on the PSD, where the PSD senses a position of the reference beams. An actuator changes the orientation of the secondary mirror to an alignment position if the position of the focused spots on the PSD is not the position for a desired alignment of the mirrors.
