The new algorithm is one of quality guided path following methods , belonging to spatial phase unwrapping methods dependent on path . its framework consists of digital weighted filtering and modulation ordering 新算法屬于空間位相展開與路徑有關的方法中利用可靠度函數尋找優(yōu)化路徑( qualityguidedpathfollowingmethod )的方法之一,由數字加權濾波和調制度排序構成。
The hybrid method can simulate accurately both the imaging and polarization - dependent diffraction characteristics of a concave grating . to meet the growing need for flattened passband in a practical wdmsystem , three design methods , namely , the tapered output waveguide structure with air - slots , the three - focal - point method and the analytical method of spatial phase modulation , are introduced to achieve a passband - flattened diffraction grating device 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制法”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(yōu)化設計方法。
