Starting from the propagation law of partially coherent light and using a typical partially coherent light , i . e . , gaussian schell - model ( gsm ) beam describing the multimode laser in practice , i present in this dissertation the research results on vectorial partially coherent light , spectral changes of partially coherent light passing through optical element , spectral switch of partially coherent light diffracted by an aperture , and the spectral anomaly of diffracted fully spatially coherent light by an aperture 本文從部分相干光的傳輸理論出發，以模擬實際多模激光的一類典型部分相干光? ?高斯-謝爾模型( gsm )光束為主要研究對象，對矢量部分相干光、部分相干光通過光學元件的光譜變化、被光闌衍射的部分空間相干光的光譜開關和被光闌衍射的完全空間相干光的光譜異常等現象進行了深入研究。
The exact location of reflection and diffraction points is essential in order to calculate the polarization components of the reflected and diffracted fields and their trajectories . then , a vector addition of the received fields is carried out to obtain the total received field strength and , subsequently , the path loss along a predetermined route 該模型基于幾何光學理論、一致性幾何繞射理論和鏡像理論,通過大量的反射和繞射射線軌跡得出源點至場點的多條路徑,然后由矢量計算求出各場點處的路徑損耗。
Our study shows that the optical potential of the diffracted light of the semi - gaussian beam is far higher than that of the evanescent - light wave , and its maximum normal velocity of the incident atoms can be far grater than that of the evanescent - light wave under the same parameters , so the blue - detuned semi - gaussian beam , as a novel atomic mirror , can be used to efficiently reflect atoms with a normal velocity of greater than 1 m / s 研究表明，半束蘭失諧高斯光束衍射光場的光學勢遠大于消逝波光場的光學勢，在同樣的參數條件下，入射原子的最大速度也比消逝波光場的大，所以作為一種新穎的原子反射鏡，半束蘭失諧高斯光束可以被用來有效的法向速度大于1m s的入射原子。
The holographic wavefront recording process records the interference pattern of the object and the reference waves , and thus forms the hologram , which simultaneously records the information about the amplitude and phase of the object waves ; the holographic wavefront reconstruction , by means of the diffracted waves , can reconstruct the original object wave from the hologram illuminated by lights 全息波陣面記錄將物光和參考光以干涉條紋記錄成全息圖，此全息圖同時記錄了物光波的振幅和相位；全息波陣面重現，就是用光波照射全息圖，通過光的衍射，從全息圖中再現出原始物體的光波。
For example , if the diffraction pattern is defocused by under - focusing the diffraction lens then the image of the specimen can be seen in both the direct and diffracted beams in the diffraction pattern and , since under - focusing the diffraction lens images a plane above the diffraction pattern , these images will not be inverted with respect to the diffraction pattern 比如，如果衍射模型是通過衍射透鏡下焦散焦的，樣本的映像就能在衍射模型中直接的衍射束中看到，但是由于衍射透鏡下焦在衍射模型之上平面成像，這些映像就不會對應衍射模型倒置。
However , the intensity gradient ( force ) of the diffracted light of the semi - gaussian beam is far smaller than that of the evanescent - light wave , so its spontaneous emission probability is greater than that from the evanescent - light one when the normal velo city of the incident atom is greater 然而，因為半束蘭失諧高斯光束衍射光場的強度梯度力遠小于消逝波光場，所以當入射原子速度較大時，原子在半束蘭失諧高斯光束衍射光場中的自發輻射幾率要大于消逝波光場。
This multi - purpose optical metering system had adopted the twyman - green interferometric system as its center , containing an advanced digital wave surface interferometry and a kind of homodyne interferometer displacement testing method with nanometer - sized capacity . at the same time , many wide - applied metering technology , for example , the diffracted field ( fringe ) measurement , co - focal lens system , optical fiber sensors and 4f ( focal distance ) space filter system which can embody the chief principle of fourier optics well , were combined into it successfully . this instrument can firstly offer and show modern optical testing method in the laboratory for majors of information processing , instrument science , measuring and testing technology and automatic technology 該多功能激光光電實驗系統以泰曼-格林干涉( twyman - green )光路作核心，包括先進的數字波面干涉技術和一種基于空間干涉原理的、納米分辨率零差干涉儀位移測量方法，同時將多種新穎、工程實用價值高的測量技術和光路如衍射測量、共焦顯微技術、光纖傳感技術以及反映傅立葉光學基本光學原理的4f空間濾波系統也組合進去。
When the beam waist wy of blue - detuned segb along the y direction is 10 mm , and its wx is decreased from 10 mm to 1mm , the absolute diffracted intensity from the segb surface will be 10 times of that from the sgb surface , which can be used to reflect an incident atomic beam with a higher normal velocity 因此，當橢圓高斯光束的w _ y = 10mm ，而w _ xw從10mn減小到1mm ，半束蘭失諧橢圓高斯光束反射面的衍射光強將比同樣參數條件下的sgb反射面的衍射光強提高了10倍。
Based on the scalar diffraction theory and the boundary condition of rayleigh - sommerfeld , the accurate on - axis propagating wave function of plane wave diffracted by small circular band is obtained by solving the first integral of rayleigh - sommerfeld 摘要從標量衍射理論出發，采用瑞利索末菲衍射邊界條件，通過求解第一類瑞利索末菲衍射積分得到平面波經圓環衍射后軸上的波函數，進而分析軸上的光強特性以及光強極值數量、位置和大小與衍射圓環內外孔徑的關系。
In considering diffraction errors there are two factors which will lead to diffracted rays originating from outside the area defined by the selector aperture , these are important in any work where a spatially accurate correlation of the diffraction data and the micrograph is required 考慮到衍射的差錯，有兩個因素決定源自選擇孔指定區域外部的衍射線，在任何工作中這些都是重要的，當衍射數據和顯微圖之間準確的空間對射被要求時。
If you were to block out the outermost diffracted orders by placing an opaque mask at the rear of the objective , you could reduce the resolution of the lines of the grating , or any other detailed object , or “ destroy “ the resolution altogether so that the specimen would not be visible 假如用不透明的遮擋物在物鏡后焦面擋住外圈衍射級的光線，線形柵格圖像的分辨率將下降，這樣完全地破壞了分辨率，標本的細節就無法看見。

The x - ray diffract was used to analyze the crystal structure of the composite . results show that after the talc was treated with blend coupling agent , the crystal structure of talc changed , and effect intercalation phenomenon 通過x射線衍射分析可知，用混合偶聯劑對滑石粉進行預處理后，滑石粉晶體結構發生改變，產生了插層現象，使pp滑石粉復合材料為納米復合材料。
At the back focal plane of the objective , the blue wavelengths from each slit interfere constructively to produce the blue area of the diffracted image of each spectrum or order ; similarly for the red and green areas ( figure 4 ( a ) ) 在物鏡的后焦面，從各個窄縫發出的藍色波長光產生增強干涉而產生各級的衍射圖像的藍色區域，紅色波長和綠色波長也一樣(圖4 ( a ) ) 。
Then we have accomplished the laser holographic interferometry experiments of shock wave diffracting double cylinders model in bend , double knives model and double cubes model . the experimental interferograms are obtained 然后，完成了彎道雙圓柱體模型、雙刀口模型、雙立方體模型的激波繞流激光全息干涉實驗，獲得了實驗干涉圖像。
Such deviated light ( as you will subsequently learn , called diffracted light ) is rendered one - half wavelength or 180 degrees out of step ( more commonly , out of phase ) with the direct light that has passed through undeviated 這種偏移光（其后我們稱之為衍射光）與直射光之間呈現半個波長或180的不同步（一般稱之為不同相位）。
For example , when light propagates through a small round hole , by computing the intensity of the diffracted light field , we can obtain the intensity distribution of fresnel and fraunhofer diffracted light field 以光線通過圓形孔徑傳播為例，對衍射后的光場分布進行數值計算，得到菲涅耳衍射和夫瑯和費衍射光場的強度分布。
However , if the plane of the selector aperture is not precisely coplanar with that of the first image , then diffracted rays originating from outside the area defined by the aperture may contribute to the diffraction pattern 然而，如果選擇孔的平面與第一次成像不是正好共面，源自孔指定區域外部的衍射線可能影響衍射模型。
