針對實際光通信應用中對通帶帶寬的需求,本文提出了「結合空氣槽的漸變輸出波導結構方法」 、 「三焦點方法」及「顯式公式空間相位調製法」三種使平面集成型衍射光柵波分復用器件獲得平頂型頻譜響應的優化設計方法。A black opal worn near the heart on a necklace made of gold is said to ward off evil and protect travelers. it is regarded as an extremely lucky stone. it has reputed healing properties, especially the power to increase mental capacities such as creative imagination and other unused powers of the mind
貴蛋白石是由無數個極度的非晶質二氧化硅小圓球組成,小圓球的直徑都相同或相近,並能在三維空間作整的排列,這些整排列的小球像光柵一樣,當白光射在上面后即發生衍射,衍射成彩色的光譜。When opal is worn as a pendant on a gold necklace and surrounded with 10 or 12 small diamonds it is believed to have excellent money - drawing power. a black opal worn near the heart on a necklace made of gold is said to ward off evil and protect travelers. it is regarded as an extremely lucky stone
貴蛋白石是由無數個極度的非晶質二氧化硅小圓球組成,小圓球的直徑都相同或相近,並能在三維空間作整齊的排列,這些整齊排列的小球像光柵一樣,當白光射在上面后即發生衍射,衍射成彩色的光譜。In this thesis, we present the law and method to generate structured illumination based on fresnel diffraction. by applying rsd theory, we analyzed the spatial distribution of fresnel diffraction field of sinusoidal grating and its available application in 3d sensing
本文詳細地研究了基於菲涅耳衍射的結構照明的原理和方法,利用角譜理論(平面波衍射理論)分析了正弦光柵的衍射光場的空間分佈及其在三維傳感中應用的可能性。Through the analysis, it is shown that : 1, while fabricating the grating, the principle of selecting the parameters is : the period should be as large as possible, the etching depth should be small and filling factor should approach to 0. 25. 2, if selecting the parameter combine the selecting principle and the requirement of concrete application, the space of selecting the parameter should be larger than before. 3, while the period to. 4a, the surface profile has no effect on the reflectivity
通過分析發現: 1 、在製作有一定特性的光柵時,光柵參數的選擇原則為:周期的取值應盡量的大,刻蝕深度的取值應盡量的小,占空比的取值應盡量靠近f = 0 . 25 ; 2 、以參數的選擇原則結合製作的具體應用要求宋選擇光柵的參數,則各個參數的優化空間更大; 3 、當光柵的周期t 0 . 4時,表面面形對反射率沒有影響; 4 、運用臨界周期點隨折射率的變化規律,可以避免由於選擇光柵周期過大而出現一級衍射,從而導致製作失敗。分享友人
