This paper utilizes masking rate theory to analyze the variation of center zero - level energy , the influence of metallic mesh ’ s different parameters on infrared transmitting ; deduces the relational expression between infrared transmitting efficiency and metallic mesh ’ s parameters ; comes to the conclusion that we can improve infrared transmitting efficiency by increasing 理论研究表明,金属网栅的周期选择在200 ~ 400 m之间,线宽不大于10 m ,是较为理想的网栅参数。最后,在实验室里用1 ~ 20ghz的信号发生器、功率放大器和频谱分析仪等雷达波检测设备,对金属网栅的屏蔽效率进行测试。
Researches focus on the identification technology of joint transform correlator after building the volume holographic storage system . it analyzes the relationship between position of related export signals and position of import images . and it gives the condition that related export signals separates from zero - level flare 在完成体全息存储系统的构建之后,开始针对联合变换相关识别技术进行研究,理论分析了相关输出信号方位同输入图像方位之间的关系,并给出了相关输出信号同零级光斑分离的条件,最后完成了联合变换相关识别系统的设计和构建。
