This work designed and fabricated an optical pickup system based on optical films using the roll-to-roll process. The design combined the advantages of the stacked and planar optical pickup system. Two blazed gratings were used as beam splitters for bending the optical path, while a cylindrical lens was used for astigmatic focus-error detection. The proposed design effectively reduces overall system configuration, component cost, and fabrication complexity.
这项工作采用卷对卷工艺设计并制造了一种基于光学薄膜的光学拾取系统。该设计结合了堆叠式和平板式光学拾取系统的优点。使用两个闪耀光栅作为分束器来弯曲光路，同时使用一个柱面透镜进行像散聚焦误差检测。所提出的设计有效降低了整体系统配置、组件成本和制造复杂性。
