In chapter 3, the elegant hermite - cosh - gaussian beams as another special case in hermite - sinusodiol - gaussian family is introduced and its propagation properties through a first - order optical abcd system are investigated. an analytical solution of the elegant herimite - cosh - gaussian beam propagating through a first - order abcd system is derived, and correspondingly, the closed - form m2 - factor, the beam width, the curvature radius and the power in bucket are presented analytically. the numerical investigations are carried out and show that the m2 - factor of elegant hermite - cosh - gaussian beam is greater than that of elegant hermite - gaussian beams and less than that of hermite - gaussian beams approximately
本文得到的主要結果可歸納為:首次用強度矩的方法研究了hermite - cosh - gaussia ( hchg )光束,得到了hchg光束的束寬、曲率半徑、 m ~ 2因子、瑞利距離等的解析表達式;用陡峭度和pib參數去衡量hchg光束的光束質量,找到了hchg光束在傳輸過程中影響光束質量的因素並得到了變化規律;證明了hchg光束在傳輸過程中的重心和對稱性都會得到保持。 -
This paper first analyzes the reason of the aliasing and the common methods for anti aliasing, and then proposes a method for adaptive anti aliasing based on the curvature radius
摘要從圖形走樣產生的機理出發,分析了圖形學中常用的反走樣方法,並在此基礎之上針對曲線的特點提出了一種基於曲率半徑的自適應反走樣方法。
