光学系统偏振特性影响抑制方法综述OA北大核心

The polarization characteristics of optical systems enable to change the polarization state of incid-ent light,thereby affecting the imaging quality and detection accuracy,and other aspects.For optical instru-ments such as telescopes and lithography lenses,polarization characteristics are important factors that de-termine the performance of these systems.Therefore,suppressing the adverse effects of polarization charac-teristics in optical systems holds significant importance for achieving high-performance modern optical sys-tems.This paper summarizes the current research status of methods for suppressing the impacts of polariza-tion characteristics in optical systems,categorizing the existing approaches into three types:polarization calib-ration,polarization compensation,and low polarization optimization design.The fundamental principles of these three methods are introduced,and the classification and discussion of each method with practical ap-plication examples are provided.Finally,the paper analyzes the connections among the three types of meth-ods and their synergistic applications,as well as discusses and provides prospects for the future development of methods to suppress the impacts of polarization characteristics in optical systems.
