光學中萬花筒圖斑的形成

Abstract

在自然界裡，可以發現一些有趣的幾何圖形。我們希望能利用電腦模擬與實務操作讓這些有趣的圖騰重現。本論文主要是利用光學方法形成各種萬花筒圖斑，論文的研究工作共分為兩個部份，分別是Quasi-Crystal圖形與Super Lattice圖形。經由平面波的疊加，將不同方向等距的平面波用干涉的方式產生圖形，利用電腦輔助研究產生所謂的準晶格與超晶格圖樣，並以實驗架構驗證其圖樣，其結果如預期跟電腦模擬圖形相吻合。

In the nature, there are some interesting geometric figures. We hoped that we can lets these interesting totem reproduction with computer simulation and practical operation. In this paper, we have demonstrated that the optical crystal, quasicrystal, and kaleidoscope beams can be generated with a collimated light to illuminate by a high-precision mask with multiple apertures regularly distributed on a ring. We also found that the super lattice patterns can be generated with the same method.
