摘要
从集成图像显示时再现的空间光学分布着手,研究了微透镜参数、记录/显示平面分辨率和成像系统空间分辨率的关系。研究结果表明成像系统的空间分辨率与微透镜的孔径和焦距大小有关。采用较小尺寸的微透镜,有助于提高成像系统的空间分辨率,但对记录/显示平面分辨率的要求随微透镜尺寸的减小以及物点深度的增加而提高。研究结果可用于集成成像系统的优化设计。
Through analyzing the reconstructed optical distribution in the displaying stage, the relationship among micro-lens parameters, planar recording resolution and spatial resolution of the integral imaging system is obtained. The results show that the spatial resolution is relevant to the pitch size and focal length of the micro-lens. Small sized micro-lens is preferred to improve spatial resolution. However, the requirement for planar recording resolution increases with the decrease of the micro-lens size. The requirement for recording resolution also increases with the increase of the object depth. The results can be used in the optimal design of integral imaging.
