A compound eye optical system design allows us to construct a compact image scanner with a large field of view and a large depth of field, both of which are beneficial for use in a copier’s flatbed scanner. Our prototypes are constructed of 32 or 28 imaging units, which are ommatidia, and the representations from the imaging units are electrically combined. Since the arrangement of the imaging units is a key factor in combining the images correctly without any loss at the boundaries, we discuss two types of arrangements along with results of their prototypes: a one-line arrangement of varying magnification imaging units and a two-line staggered arrangement of telecentric imaging units. We also discuss the effectiveness of wavefront coding (WFC) in suppressing chromatic aberration, which is caused using cheap refractive imaging units, along with experimental results of applying both cubic- and quartic-phase-modulated WFC.

最佳配置的复眼图像扫描仪，用于通过波前编码进行图像合成和抑制轴向色差

复眼光学系统设计使我们能够构建具有大视野和大景深的紧凑型图像扫描仪，这两者都有利于在复印机的平板扫描仪中使用。我们的原型是由32个或28个成像单元构成的，它们是眼药水，并且成像单元的表示是电结合的。由于成像单元的布置是正确组合图像而不会在边界处造成任何损失的关键因素，因此，我们讨论了两种类型的布置及其原型结果：一排不同放大率成像单元的布置以及两幅放大率的成像单元。远心成像单元的直线交错排列。我们还讨论了波前编码（WFC）在抑制色差方面的有效性，而色差是由廉价的折射成像单元引起的，
