  • Artificial beacon is a key issue of adaptive optical systems.For the air-borne optical systems,artificial beacon is used to sample the wavefront distortion which is mainly caused by the atmospheric turbulence and the change of gravity field and temperature field.A kind of beacon composed of both Rayleigh and sodium guide stars is presented to detect the wave-front.A numerical model is discussed.The corresponding simulation result is given.It is found that the adaptive optics based on the beacon composed of the two kinds of laser guide stars are feasible for the wave-front detection of air-borne optics.

Abstract: Artificial beacon is a key issue of adaptive optical systems.For the air-borne optical systems,artificial beacon is used to sample the wavefront distortion which is mainly caused by the atmospheric turbulence and the change of gravity field and temperature field.A kind of beacon composed of both Rayleigh and sodium guide stars is presented to detect the wave-front.A numerical model is discussed.The corresponding simulation result is given.It is found that the adaptive optics based on the beacon composed of the two kinds of laser guide stars are feasible for the wave-front detection of air-borne optics.
