The main works and contributions achieved in this dissertation are concluded as follows : 1. based on the scalar diffraction theory, the mathematical model of optical configuration of transmissive grating interferometer is established. it indicats that moir interference fringes is affected by many parameters, such as grating pitch, light wavelength, light beam size and incidence angle, etc. the variation that the width, intensity, orientation and contrast of moir interference fringes along with every parameter is numerically analyzed
主要的研究內容和所取得的成果可歸納如下: 1 .基於標量衍射理論,建立了透射式光柵干涉儀光路的數學模型,分析了透射式光柵干涉儀的莫爾干涉條紋與光柵柵距、光柵開口比、光波波長、光斑尺寸、光束入射角等多個參數的關系。This method has some characters : during recording of the transmissive holograms the holographic grating placed in front of the holographic plate closefittingly is used as a spectroscope. the transmissive wave is served as the object wave and the diffraction wave through the holographic grating or the deflective reflect wave produced by the silicon slice is served as the reference wave, therefore the hologram is named as self - reference image hologram. the recording results are the off - axis holograms and the twin images can be separated successfully
在記錄透射型全息圖時,將全息光柵緊貼置於記錄干板之前,而光柵起到了分光的作用,直透波作為全息圖的物光波,參考光是物光通過光柵后產生的衍射波;記錄反射型全息圖時將矽片置於記錄干板之後,利用反射矽片產生離軸參考光,因此系統僅需一束照明光束,參考光來自物光本身,因此稱之為自參考像全息圖。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,線形柵格圖像的解析度將下降,這樣完全地破壞了解析度,標本的細節就無法看見。This paper also discussed the factors that influenced the diffraction efficiency of scattering object, and proposed the amount of refraction index modulation was very small, the diffraction efficiency was mainly determined by chemical treatment
並指出體積光柵效應對透射全息衍射效率是有貢獻的,討論了影響散射物體全息衍射效率的問題,最後指出在一般情況下,調制折射率是一個很小的量,化學處理對它起著關鍵性的作用。The first section includes the theoretical and numerical analysis for diffractive optics elements and the second one gives the results of the fabrication experiments of diffractive optics elements. in the first section, we analyzed the antireflection of the diffraction optics elements. binary optics processing methods may be applied to a glass or silicon substrate to generate an array of small columns in order to enhance transmission
在理論分析的部分,本論文完成的主要工作是用耦合波理論分析了在玻璃或硅基底上製作具有亞波長結構的圓柱形網格陣列以實現對入射光的增透作用,為此而編寫的程序實際上也可以用來分析計算單位周期內具有任意麵形的網格光柵的電磁場衍射特性。分享友人
