Other Abstract

Tip-tilt disturbance of atmospheric turbulence leads to the angle-of-arrival fluctuations when a beam is propagating through such an atmosphere. The laser beam is propagating through the turbulent atmosphere twice in the cases of satellite laser ranging and laser guide star. Different locations of geometric layouts of laser transceiver lead to the difference in correlation of tip-tilt fluctuations between laser launch and receive paths, and affect the variations of angle-of-arrival fluctuations in the end. Based on the geometry of laser transceiver, the tip-tilt correlation between two separated apertures is developed by using the wavefront expansion on the Zernike polynomials. The changes of the tip-tilt correlation due to the geometrical limit of common optical path system and non-common optical path system are analyzed. Finally, the impacts of geometric layouts of the different laser transceivers on the angle-of-arrival fluctuations are discussed.
