不漏光圓形彎曲光管之設計與分析

Abstract

本論文主要在於針對等角螺旋線型彎曲不漏光光管作延伸進而設計出不漏光圓形彎曲光管。對於光管的應用而言，彎曲的光管外型常在傳遞的過程中伴隨著漏光的產生，對此前人透過對黃金螺旋線的觀察設計出了等角螺旋線型彎曲不漏光光管得以使得光線在此光管內部傳導時每次的轉向都伴隨著全反射的發生，所以此種彎曲光管得以有百分之百不漏光的性質，但是卻由於其接口形狀所造成的幾何限制影響了此光管與其它光管在連接方式上的應用，因此，透過前人所研究設計出的等角螺旋線型彎曲不漏光光管的了解進而設計出了不漏光圓形彎曲光管，此光管不僅保有其光管彎曲處導光百分之百不漏光的性質並且加以改善了等角螺旋線型彎曲不漏光光管當中的接口問題，而後我們還有對於此不漏光圓形彎曲光管的不漏光原理加以探討並架設實驗加以比較軟體模擬結果

This thesis is primarily based on the equiangular-spiral non-loss bent lightpipe then extends to design the circular non-loss bent lightpipe. For the applications of the lightpipe, the bent of the shape of lightpipe often accompanies the loss of the light as propagated. For this problem, the former had design the equiangular-spiral non-loss bent lightpipe by the observation of golden spiral. This design could make the lights turn with the condition of the total internal reflection as it propagates in the pipe. So this kind of bent lightpipe has the property of 100% non-loss. But the geometrical limitation caused by the shape of interface affects the application of the lightpipe in connection with other pipes. What we have done is to design the circular non-loss bent lightpipe with the understanding of the equiangular-spiral non-loss bent lightpipe. This pipe keeps the property of 100% non-loss at the bent part of lightpipe, but also improves the problem of the shape of interface in the equiangular-spiral non-loss bent lightpipe. After these discussions we also have the observation of the theorem of non-loss for the circular non-loss bent lightpipe and set up the experiment to compare the result with the simulation by the program.
