中文拼音 [jǔkǒngyǎnshè]
矩孔衍射
英文
rectangular aperture diffraction-
Two spherical waves and multiple spherical waves interference, and yang ' s interference experiments are simulated by using different methods. two spherical waves interference is focused on the on - plane or out - plane of the spot light source plane and the observing plane. then, we analyze how the temporal coherence of optical waves influence the contrast of the interference pattern
用光波波前疊加的方法實現了對兩列球面波干涉、多光束干涉等實驗的模擬;用傳播矩陣描述衍射光波波前傳播的方法對楊氏雙縫和雙孔干涉實驗進行了模擬,並具體詳細地分析了單縫衍射對雙縫干涉的影響;另外還分析了光場的時間相干性對干涉條紋反襯度的影響。The fresnel and franhufer diffraction patterns, of regular shapes screen such as slits, rectangular apertures, circle apertures, discs, triangle apertures, ronchi gratings, and some irregular shapes screen, are observed in the different propagation distance. this clearly gives the relation and difference of the two diffraction patterns
具體分析了規則形狀如單縫、矩孔、圓孔、圓盤、三角孔、黑白光柵及一些不規則形狀等孔徑的菲涅耳衍射和夫瑯禾費衍射圖樣強度分佈,為深入理解菲涅耳衍射和夫瑯禾費衍射及其內在聯系與區別提供了理論依據。
