    摘要: 在本論文中,我們利用自建程式可以快速設計集光模組的非球面鏡的曲率(curvature)和圓錐常數(conic constant),也可以快速簡單分析不同規格集光模組;除了非球面鏡的集光模組,也可以設計出曲線為數多個直線組合的雙反射多環型集光模組,這種集光模組具有簡單易製造,成本低廉,而且也可以做成大型的集光模組,成本也較低。 在雙反射非球面鏡的部份,分為兩種型式,一種為拋物面-雙曲面,另一種為拋物面-橢圓面,皆利用自建程式求出各種規格並做分析。針對不同f/#做NA與集光比、NA與光斑大小、NA與曲面二孔徑、NA與兩曲面距離等。在某種特定條件下,具有最高的集光比。而這兩種在所有規格中,拋物面-橢圓面具有比拋物面-雙曲面高一些的集光比,拋物面-橢圓面在f/0.25具有最高集光比8404,拋物面-雙曲面在f/0.25也具有最高集光比8029。設計出不同規格的模組之後,再對追蹤角度的誤差最分析,以及製造公差的分析,根據追蹤角度偏差對集光比的影響來判斷此集光模組在角度偏差超過某角度時,會使集光比大幅降低。 在雙反射多環型集光模組部分,同樣以自建程式求出在不同條件下的規格,搭配光機軟體ASAP模擬實際太陽光集光的效果。並且也對這種集光模組做追蹤角度誤差分析。由於雙反射多環型集光模組有些製造上的缺點,因此就修改原來的雙反射多環型集光模組,改良成更容易製造的雙反射多環長度給定型。由於在設計上有許多參數,在本論文中尚未找到最佳化的參數,只是提供了設計方法以及設計的參數,因此未來必須找到最佳化的參數。 In this thesis, we use our program to design quickly aspheric curvature and conic constant of solar concentrator, also quickly and simply analyze all kinds of solar concentrators. Not only to design aspheric concentrators, but also to design another type which curve is composed of straight line. The concentrator is easy to manufactures and is quite cheap. It also can make a large concentrator, and it is also cheap. In the part of double reflective aspheric mirror, it includes two type. One is paraboloid-hyperboloid, and other is paraboloid-ellipe. The two types both use our program to design all kinds and to analyze. To analyze concentrator ratio, spot size, the second surface size and distance of the two surface. In specific condition, the two types have the highest concentrator ratio. All kinds of solar concentrator, the concentrator ratio of paraboloid-ellipe concentrator is the highest. The paraboloid-ellipe concentrator has the highest concentrator ratio which is 8404. The paraboloid-hyperboloid concentrator has the highest concentrator ratio which is 8029. After designing concentrator, we must analyze error angle of tracking and manufacture tolerances. According to the influence of error angle of tracking to consider that the concentrator has much concentrator ratio drop above a special error angle of tracking. In the part of many rings type double reflective concentrator, also use our program to design all kinds. We use ASAP to simulate that real sunlight concentrate. We also must analyze error angle of tracking. The many rings type concentrator have some manufacture defect, so alter the many rings type concentrator to become amelioration type which is more easy to manufacture.
