  • 擴增實境產品在今日不斷的推陳出新,然而大多數的產品擁有輻輳調節衝突(VAC, Vergence Accommodation Conflict)的問題,且其虛擬影像大多缺乏深度資訊。本研究為解決上述問題,使用CodeV光學模擬系統進行光學設計變焦近眼顯示器系統,本光學設計包含了使用液態透鏡為元件的變焦系統以及使用自由曲面為結構的膠合鏡片目鏡,以達到放大虛擬影像但不影響現實影像的效果。實作上使用MGSA演算產生之全像影像作為擴增實境系統中之虛擬影像,並以spatial light modulator將其相位資訊呈現於LCoS面板,使用透鏡結構再放大影像並使用液態變焦透鏡達到虛擬影像擬真化的效果。本研究將設計出之光學系統針對不同成像平面之虛擬影像進行各種深度之影像品質評估,包含了影像畸變的程度以及調制轉換函數的品質,並在實驗中檢驗放大率與影像對比度水準。希望進行各樣分析後,得到一個最適合使用者的擴增實境產品,在不同位置上依然擁有良好的視覺感受。


    Nowadays, augmented reality products brings forth the new through the old. But most of them have the VAC, Vergence-Accommodation Conflict, and absence of depth information. To solve these problem, this essay construct a zooming swift optical system. simulating the Merged reality system structure by the Code V. This structure consisted with the focus tunable lenses zooming system and light-guided eyepiece. The image source is a hologram and its phase is generated from the Modfied-Gerchberg Saxton Algorithm (MGSA). The image evaluation including distortion, MTF, magnification and contrast. The optimal system will be realized after those analysis above, bringing the accurate vision effect to the user in different depth.
