本研究使用純相位式矽基型液晶空間光調製器(Liquid Crystal on Silicon-Spatial Light Modulator, LCoS-SLM)作為元件，通過電子訊號對光訊號進行調製。該調製器利用外加電場影響液晶的電光效應，從而改變液晶的折射率，進而調整光波的相位、振幅或偏振態。實驗中，我們主要透過偏振片與檢偏片(Polarizer & Analyzer)來調整該液晶空間光調製器成為相位調製器。利用電腦生成全像圖(Computer generated holography, CGH)的方法，我們可以利用相位延遲的特性調製出軌道角動量 (orbital angular momentum, OAM)光束，以進行訊息的傳遞。相較於傳統光學元件，全像圖的應用可以減少所需的光學元件數量，並透過疊加不同的全像圖來實現多種不同的光學元件功能。本研究主要將 OAM 光束與傳統高斯光束進行性能比較，在不同環境下進行實驗。藉由評估兩者在空氣、水和玻璃等不同介質中的穩定性、傳輸性能和容忍度，我們得出了它們在不同環境下的性能表現。這些結果有助於更深入理解 OAM 光在各種應用場景下的適用性。.

520 3 $a This study utilized a pure phase-type silicon-based liquid crystal spatial light modulator (LCoS-SLM) as the component, modulating optical signals through electronic signals. The modulator exploits the electro-optic effect of liquid crystals under an external electric field to alter the refractive index, thereby adjusting the phase, amplitude, or polarization state of light waves. Polarizers and analyzers were primarily employed in the experiment to configure the liquid crystal spatial light modulator as a phase modulator. By employing computer-generated holography (CGH), we could utilize the phase delay property to modulate orbital angular momentum (OAM) beams for message transmission. Compared to traditional optical elements, the application of CGH reduces the number of required optical components and enables the realization of various optical functionalities through the superposition of different holograms. This study primarily compares the performance of OAM beams with traditional Gaussian beams, conducting experiments in different environments. By evaluating their stability, transmission performance, and tolerance in various media such as air, water, and glass, we obtained insights into their performance in different environmental conditions. These results contribute to a deeper understanding of the applicability of OAM light in various scenarios..
