Optics compensation
WebThe influence of the Gaussian beacon’s wavelength on the compensation of the OAM beams at 1560 nm is experimentally studied. It is found that the compensation performance degrades slowly with the increase in the beacon’s wavelength offset, in the 1520–1590 nm band, from the OAM beams. WebFeb 2, 2024 · Adaptive optics pre-compensation of free-space optical communications uplink from ground to space is complicated by the “point ahead angle” due to spacecraft velocity and the finite speed of light, as well as anisoplanatism of the uplink beam and the wavefront beacon. This Letter explores how pre-compensation varies with the number of …
