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 理論研究表明,金屬網柵的周期選擇在200 ~ 400 m之間,線寬不大于10 m ,是較為理想的網柵參數。最后,在實驗室里用1 ~ 20ghz的信號發生器、功率放大器和頻譜分析儀等雷達波檢測設備,對金屬網柵的屏蔽效率進行測試。
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 在完成體全息存儲系統的構建之后,開始針對聯合變換相關識別技術進行研究,理論分析了相關輸出信號方位同輸入圖像方位之間的關系,并給出了相關輸出信號同零級光斑分離的條件,最后完成了聯合變換相關識別系統的設計和構建。
