面向空间光通信的电光材料光束偏转研究现状及应用前景OA

Electro-optic beam deflection technology possesses advantages such as low power consumption,miniaturization,and good controllability.Compared with mechanical beam deflection,acousto-optic beam deflection,and liquid crystal beam deflection technologies,it is more easily able to meet the practical applic-ation requirements of rapidity and stability in space laser communication.This paper systematically summar-izes the domestic and international research progress of several widely applied novel electro-optic materials(such as lithium niobate,lead lanthanum zirconate titanate,and potassium niobate tantalate)in the field of beam deflection.Based on the intrinsic deflection characteristics of different electro-optic materials,the fea-tures of corresponding beam deflection technologies are comprehensively analyzed and compared from the perspectives of application configurations and key performance metrics.Furthermore,the application pro-spects of these electro-optic material-based beam deflection technologies in space optical communication are discussed,the urgent challenges that need to be addressed currently are highlighted,and the directions for fu-ture research endeavors are clarified.
