摘要：
This paper presents a multi-beam scanning method for liquid crystal optical phased arrays (LC-OPAs) based on greedy genetic algorithm to solve issues of long scanning periods and low capture efficiency associated with single-beam scanning. Multiple LC-OPAs are utilized to generate independent beams with equal scanning areas. To efficiently scan and track multiple dynamic targets, a greedy genetic algorithm-based multi-beam scanning scheme is proposed. The scheme assigns targets to each beam based on target size, position, and velocity information, optimizing the scanning order to maximize target capture probability. A liquid crystal optical phased array multi-beam scanning platform is built, and the proposed scanning method is simulated and experimentally verified under various target numbers, target movement speeds, and spot radii. The results demonstrate that the proposed method can not only effectively reduces the scanning cycle but also improves the capture efficiency of dynamic targets. © 2023 China Ordnance Society.
