以Tracepro輔助科學研究的視覺化

Abstract

我們使用光學模擬軟體-Tracepro，對光學元件、LCD導光板以及不同形狀光導管做光學特性的模擬。光通過各種透鏡之後可以從光跡圖和輻照圖，清楚看出光線會聚、發散或形成空心光束的樣貌。LED光源進入導光板之後，產生的hot spot現象，由模擬的結果顯示出：在導光板入光側製作V型和U型微結構，可以降低hot spot的影響；V型結構在特定頂角範圍中仍有強度分佈不均勻的問題，而U型結構則無此問題存在。將雷射光打入不同形狀光導管的模擬中，可以看到不同(p,q)圖形產生，而藉由軟體的幫助，在光導管內部產生的圖形也可以清楚地呈現出來。

We simulated the propagation of light passing through lenses,light guide plate and light pipe with optical simuation software Tracepro. The proporties of lenses can be observed with light tracing graphs and irradiation plots. We can reduce the effect of hot-spot in light guide plate by using micro structures of V-shape or U-shape. It is more effective to increase the uniformity of light guide plate by using structures of U-shape with intervals. The irradiation plots which shows graphs of specific (p,q) mode inside several shape of light pipes are observed with Tracepro.It is not easy to observe the graphs inside light pipes with experiments. However, we can easily do it with Tracepro.
