传统的积分成像系统利用具有固定焦距和孔径尺寸的小透镜阵列。我们提出了一种时分多路复用积分成像方法，通过使用具有不同焦距和孔径大小的小透镜阵列显示三维图像，从而增强三维图像的焦深和分辨率。计算了该方法的非均匀小透镜参数（焦距和孔径）。我们的理论分析表明，焦深和分辨率的显着改善，可以获得与所提出的技术，（C）2003年美国光学学会。
Conventional integral-imaging systems utilize lenslet arrays with fixed focal lengths and aperture sizes. We propose a time-multiplexed integral-imaging method that enhances both the depth of focus and the resolution of a three-dimensional image by displaying it with an array of lenslets with different focal lengths and aperture sizes. The nonuniform lenslet parameters (focal lengths and aperture sizes) for our method are calculated. Our theoretical analysis indicates that significant improvements in both depth of focus and resolution can be obtained with the proposed technique, (C) 2003 Optical Society of America.
