Title:
OPTICAL ATP ANTENNA AND OPTICAL SIGNAL PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/231504
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present application is an optical acquisition, tracking, pointing (ATP) antenna, used for implementing the distribution of an annular Gaussian beam by means of a pyramid lens, thereby reducing costs of the optical ATP antenna. The optical ATP antenna comprises an input light source module, a pyramid lens, and an optical imaging module; and the central axes of the input light source module, the pyramid lens and the optical imaging module coincide. The pyramid lens is used for shaping, into a first annular Gaussian beam, a first Gaussian beam emitted by the input light source module, and transmitting the first annular Gaussian beam to the optical imaging module. The optical imaging module is used for expanding the first annular Gaussian beam into a second annular Gaussian beam, and transmitting the second annular Gaussian beam to a lower optical path, the diameter of the second annular Gaussian beam being larger than that of the first annular Gaussian beam.
