本論文提出使用矽基液晶元件為空間光調變器分別進行基於振幅調變及相位調變之微投影通訊架構之研究與實現。
在振幅調變之微投影通訊架構中，本論文使用RGB LED為光源，透過極化調變影像系統之設計來分別進行投影與通訊功能之執行，並透過基頻調變訊號之設計與應用來進行此微投影通訊架構之光數據傳輸測試。從量測結果可以發現使用16-QAM的調變技術，此微投影通訊架構可以在投影與通訊同時執行時，在位元錯誤率為〖10〗^(-3)時達到接近1 Gbps的資料傳輸率。
在相位調變之微投影通訊架構中，本論文使用藍光雷射作為光源，並提出GS演算法之優化程序來進行電腦全像之設計以使用空間光調變器進行多點通訊之實現。在多點通訊之實現中，本論文針對一維排列之三點、六點以及二維排列之四點、九點分別進行短距離與長距離之能量分布均勻度之分析。從量測結果可以發現，透過本論文所提之GS演算法優化程序，可以有效改善多點傳輸能量分布之均勻度，進而在光數據傳輸測試中，可以有效提升接收端中各點可以傳輸之最低資料傳輸率。

In this thesis, the research of amplitude modulated and phase modulated micro-projection enabled short-range communication architecture which offers simultaneous micro-projection and high-speed data transmission, serving as an alternative short-range communication (SRC) approach for personal communication device (PCD) application in 5G is presented and experimentally demonstrated.
In order to make the proposed system architecture transparent to the future possible wireless data modulation format, baseband modulation schemes such as multilevel pulse amplitude modulation (M-PAM), M-ary phase shift keying modulation (M-PSK) and M-ary quadrature amplitude modulation (M-QAM) which can be further employed by more advanced multicarrier modulation schemes (such as DMT, OFDM and CAP) were used to investigate the highest possible data transmission rate of the proposed system architecture.
In amplitude modulated micro-projection architecture, the results demonstrated that an aggregative data transmission rate of 892 Mbps and 900 Mbps at a BER of 10-3 can be achieved by using RGB-LEDs with 16-QAM modulation scheme when data transmission were performed with and without micro-projection simultaneously
In phase modulated micro-projection architecture, multi-spot communication were also investigated and an optimized Gerchberg-Saxton Algorithms was proposed to improve the spot uniformity and the results shown that a significant performance improvement has achieved either in a one-dimension or two-dimension spot array generations.
