Abstract: Embodiments of this application disclose example optical acquisition, tracking, pointing (ATP) antennas, to implement distribution of an annular Gaussian beam by using an axicon. One example optical ATP antenna includes an input light source, an axicon, and an optical imaging assembly, and central axes of the input light source, the axicon, and the optical imaging assembly coincide. The axicon is configured to: shape a first Gaussian beam emitted by the input light source into a first annular Gaussian beam, and transmit the first annular Gaussian beam to the optical imaging assembly. The optical imaging assembly is configured to: expand the first annular Gaussian beam into a second annular Gaussian beam, and transmit the second annular Gaussian beam to a lower optical path, where a diameter of the second annular Gaussian beam is greater than a diameter of the first annular Gaussian beam.
