Abstract
A lightweight scalable multi-user optical antenna includes a coarse tracking liquid crystal, an optical filter, a beam shrinking system, a fine tracking liquid crystal and a beam splitter which are arranged in sequence and are located on a same central axis; further includes a data analysis and instruction system, a coarse tracking liquid crystal controller, a fine tracking liquid crystal controller, j single-mode optical fibers, and an imaging system and a dichroic coupling system which are respectively arranged in two emergent light paths of the beam splitter; and can be used to receive and transmit the laser beams of j communication targets. When the number of users increases, only sub regions of the coarse tracking liquid crystal and the fine tracking liquid crystal need to be added, and no additional components need to be added, and the lightweight scalable multi-user optical antenna has strong scalability.
