中文摘要 本論文應用太陽盲區紫外光波段於光學雷達及非直視性通訊。太陽盲區紫外光波長介於200至280nm之間,因為臭氧層的強力吸收,此波段幾乎無法到達地球表面,所以稱作「太陽盲區」。此波段分別與上層和下層的大氣層成分有強烈反應,產生特殊的吸收與散射特性,適合運用於需要保密性及抗干擾性之遙測與通訊系統。
光學雷達部分將建立光強度與距離的關係,並考慮多種不同的雜訊以計算訊號噪音比;非直視性通訊部分將以幾何模型建立通訊方程式,並推導路徑損失、帶寬以及位元錯誤率。方程式分別建立完成後,進而考慮光學元件參數、幾何參數、大氣參數等,以電腦輔助模擬光學雷達以及非直視性通訊的各項表現,探討此波段是否能達到保密性及抗干擾等特點。另外,以市面上可取得的光學雷達測距儀驗證真實資料計數率與模擬之光子計數,並且開發陣列掃描功能,可作為往後光學雷達之設計參考。
英文摘要 The purpose of this study is to investigate the performance of solar-blind ultraviolet light applied to the LIDAR (Light Detection and Ranging) system and NLOS (Non-Light-of-Sight) communication system. Solar-blind ultraviolet light with wavelengths from 200nm to 280 nm, due to the absorption by the ozone layer, can hardly reach the earth's surface, hence the name "solar-blind".
Solar-blind ultraviolet light reacts strongly with the components of the upper and lower layer atmosphere and produces unique absorption and scattering characteristics. It is suitable for use in telemetry and communication systems that require confidentiality and interference immunity.
The LIDAR section will establish the relationship between light intensity and distance, and consider a variety of different noises to calculate the signal-to-noise ratio. The NLOS communication part will establish the communication equation with the geometric model and derive the path loss, bandwidth, and bit error rate.
After the equations are established, we will analyze the performance of LIDAR system and NLOS communication system, considering optical component parameters, geometric parameters, and atmospheric parameters, etc., to investigate the feasibility of solar-blind ultraviolet light towards achieving confidentiality and interference immunity.
Furthermore, we use the commercially available single-photon avalanche detector (SPAD) range finder to verify the signal rate from experimental results and the photon count from simulations. Also, we develop the scanning function of the SPADs array, which can be used as a design reference for the backward LIDAR.
