摘要： An off-axis telescope having a primary optical element configured to reflect an energy beam from an optical reference source that emits the energy beam along an optical path. The telescope includes angle sensors arranged on a periphery of the primary optical element to determine angular motion of the energy beam from the optical reference source. The angle sensors are operable to be biased to positional settings associated with a desired pointing direction of the energy beam. A secondary optical element is arranged in the optical path and translated along three orthogonal axes. A plurality of steering mirrors arranged between the optical reference source and the secondary optical element is configured to be tilted in response to a control signal. A controller auto-aligns the telescope by at least translating the secondary optical element and tilting the steering mirrors via the control signal using at least inputs from the plurality of angle sensors.

摘要： A high-energy beam is precompensated by a process including receiving a high-energy beam from a source and energy from a target. The target energy includes wavefront aberrations related to atmospheric and other external disturbances encountered along a distance separating the target. A correction signal is determined responsive to the high-energy beam and the target energy. The correction signal is also configured to pre-compensate for wavefront aberrations related to the atmospheric and other external disturbances and to cancel aberrations introduced by the adaptive optics techniques. A wavefront of the outcoupled high-energy beam is adjusted responsive to the determined correction signal. A beam control system includes three adaptive optics servo loops and an aperture-sharing element. The arrangement is adapted to self-cancel internal optical-path-difference errors in the outcoupled beam and to pre-compensate the outcoupled beam according to a conjugate of the wavefront aberrations related to atmospheric and other external disturbances.
