    摘要: A free-space optical communication terminal includes an optical head, a steering device configurable to move the optical head, and one or more controllers. The optical head includes a position sensitive detector configured to measure a position of a received laser beam, a micro-gimbaled deformable mirror configurable to modify a wavefront of the received laser beam, and a wavefront sensor configured to measure a wavefront profile of a portion of the received laser beam. The one or more controllers are configured to control the steering device to correct aberrations within a first frequency band, control the micro-gimbaled deformable mirror to correct aberrations within a second frequency band based on the measured wavefront profile, and control the micro-gimbaled deformable mirror to correct aberrations within a third frequency band higher than the second frequency band.
