Diffractionlimited aspheric collimation lens
衍射極限非球面準直透鏡When a larger waist w of the incident gaussian beam and a shorter focal length / of the lens are chosen, we can obtain an extremely - small dark spot size of the focused hollow beam, even approach the diffraction limit
當選擇較大的入射準直高斯光束的束腰w _ 0和較短的薄透鏡焦距f時,可以在焦平面上產生一個很小的dss (或束半徑r _ 0 ) ,甚至可以接近衍射極限。In order to break through the choke point of the traditional design of a telephoto lens, how to eliminate aberrance by means of hybrid refraction - diffraction was studied from the view of the phase polynomial of diffractive surface and phase transformation polynomial of general lens
摘要為了突破長焦物鏡傳統設計中的局限性,從衍射面的相位多項式出發,結合一般透鏡的相位變換式,對折衍混合消像差理論進行了探討。With the more modern ` four - lens ' microscopes the added flexibility removes this restriction and selected area diffraction is typically available for magnifications within the range 1 0 000 to 500 000 times
更先進的四透鏡顯微鏡增加的適用性消除了這個限制,選區衍射對在10000到500000倍的放大中有代表性作用。Because the feature size of subwavelength diffractive microlens is smaller than the incident wavelength, scalar diffractive theory cannot be used to the analysis. it also precludes rigorous vector coupled - wave theory for its finite and aperiod structure
由於亞波長衍射微透鏡的特徵尺寸小於入射波長,因此不能採用標量衍射理論來分析,又由於它是有限非周期的結構,嚴格的耦合波方法對它也不適用。The numerical reconstruction algorithm of digitally sampled holograms, deduced from the scalar quantity diffraction theory, is investigated. the serious recording limitations due to the finite size and resolution of ccd are detailed discussed
根據標量衍射理論,討論了利用菲涅耳衍射公式對數字無透鏡傅里葉變換全息術的數值實現,並進一步討論了ccd參數對數字全息圖記錄的限制條件。In the dissertation body - of - revolution finite - difference time - domain method ( bor fdtd ) is employed as the theory mode for the analysis of axially symmetric subwavelength diffractive microlens
論文中將旋轉體時域有限差分法( borfdfd )作為分析具有軸對稱結構的亞波長衍射微透鏡的理論模型。First, we propose a novel and simple mirror to reflect atoms by using intensity gradient induced by a blue - detuned semi - gaussian laser beam. the diffraction characteristics of an incident gaussian beam by straight edge bounding a semi - infinite opaque plate are investigated from kirchhoff scakr wave theory in the fresnel limit
