本論文分別透過使用振幅調變與相位調變之微投影架構與可見光通訊技術之結合，來進行可應用於第五代行動通訊(5G)裝置間短距離通訊技術之研究。
為實現指向性通訊與分時分波多工(Time and Wavelength Dividsion Multiplexing, TWDM)傳輸之技術，本論文分別在基於振幅調變與相位調變之微投影通訊架構中，透過使用矽基液晶元件為空間光調變器進行波前調製與動態光學濾波器之設計與實現。
從系統損耗分析得知，使用相位調變之微投影通訊架構不論在發射端進行指向性通訊之實現或是在接收端進行動態濾波器之設計以實現分時分波多工傳輸之技術，均有較高之傳輸效率與較低之雜訊干擾(Crosstalk)。
在數據傳輸測中，不論在振幅調變或是相位調變之微投影通訊架構中，在滿足位元錯誤率為10-3時，資料傳輸效能均優於目前商業使用中的短距離通訊之技術。

An experimental study of visible light communications based on amplitude and phase modulated micro-projection architecture for short range 5G device and device communication is presented in this thesis.
An Liquid Crystal on Silicon (LCoS) device was used as a Spatial Light Modulator (SLM) to modulate wavefronts for the implementation of beam steering and dynamically optical filter design in the wavelength division multiplexing, WDM-based micro-projection enabled communication architectures.
From the analysis of the system light loss, phase modulated micro-projection enabled communication architecture has a higher transmission efficiency and a lower crosstalk than amplitude modulated micro-projection enabled communication architecture when the functionality of beam steering and dynamically optical filtering were performed.
In the digital data transmission tests, the measurement results shown that the proposed micro-projection enabled communication architectures either based on amplitude or based on phase modulation, all have a better data transmission performance than the current development of short-range communication technologies.
