Abstract: | 在這篇論文中,我們製作出一個用於光學辨識系統的可獨立調變貓眼回射器,首先我們對於元件的接收角進行模擬,根據模擬結果來設計回射器元件,並且增加貓眼回射器的密度以及設計可獨立調變的電極,讓貓眼回射器能產生動態的調變。高分子分散型液晶(Polymer-dispersed liquid crystal)薄膜是貓眼回射器的調變機制,所以我們比較液晶薄膜的厚度對於光的穿透率。最後根據模擬結果所製作出的元件進行調變回射光、不同光源的調變效果、回射器的觀察角、回射器的接收角的研究。 In this thesis, we made independently addressed tunable cat’s eye retro-reflector array for optical identification system. First, we simulated the operating angle of the device. According to the result of simulation to design the retro-reflector element. we increase the filling factor of the array and design independently addressed tunable electrodes. The cat’s eye retro-reflector array is able to demonstrate dynamic text images. Polymer-dispersed liquid crystal (PDLC) film is a cat's eye retro-reflector modulation mechanism. . Therefore, we compared the thickness of the PDLC film with light transmittance. Finally, we made the device that according to simulation result. And we research the modulation of retro-reflection light, the effect of different light source, viewing angle and operating angle of the device. |
