| dc.description.abstract | 本論文設計出一種可藉由凹摺的方式由平面的結構轉成立體的Corner Cube Retroreflector (CCR)，並設計出兩種不同功能的CCR。可調變CCR可以藉由調變CCR鏡面的角度達到自由空間光通訊的效果；而不可調變CCR則可以利用卡榫結構固定CCR。本論文還開發出以線切割技術，以及以3D列印技術製作CCR光學元件的製程，以此兩種方法可降低製作CCR光學元件的成本。為了符合線切割製程中的限制，適時的修改設計使元件能順利製作。而在3D列印製程中則需透過改善表面反射率使元件效率提升。使用線切割製程所製作的CCR元件回設效率較低。而使用3D列印製程所製作的CCR元件回設率較高，並可使用電控平移台進行光訊號的調變。本論文並利用光學模擬軟體解釋製程中遇到的問題，以及量測的結果。 | zh_TW |
| dc.description.abstract | In this paper, we design a Corner Cube Retroreflector (CCR), which can transform from two-dimensional structure into three-dimensional structure by being folded (origami), and there are two different types of CCR. Tunable CCR can be used in free-space optical communication by adjusting the angle of CCR mirror. The latch in the fixed CCR can confine the angle of the CCR. This paper also developed producing processes with Wire Electrical Discharging Machine (WEDM) technology, as well as 3D printing technology to produce the CCR. We also modify the design of the CCR to meet the restrictions in the wire cutting process so that the components can be produced smoothly. In the 3D printing process, we improve the surface reflectivity to improve the efficiency of the components. The reflectivity of the CCR, made by WEDM, is lower than the CCR, made by 3D-printing. The CCR, made by 3D-printing, can modulate optical signal with a motorized translation stage. We also explain the problems encountered in the process, as well as the results of measurement with optical simulation software. | en |
