论文摘要
我们使用直接激光器写作制造两种100%填充因子复合眼结构,包括每个微芯单元的焦距相同的常规复合眼(CVCE),以及专门设计的共聚焦复合眼(CFCE)。对于CFCE,每个Microlens单位的焦距由其位置确定,等于Microlens单元和图像传感器之间的距离。在这封信中,测试并比较了CVCE和CFCE的光学特性。已经发现,与CVCE相比,CFCE可以提高聚焦效率约7%,将成像区域扩大约25%,并且在视野边缘具有更好的成像质量。
We fabricate two kinds of 100% fill factor compound eye structures using direct laser writing, including conventional compound eyes (CVCEs) with the same focal length of each microlens unit, and specially designed confocal compound eyes (CFCEs). For CFCEs, the focal length of each microlens unit is determined by its position and is equal to the distance between the microlens unit and the image sensor. In this letter, the optical properties of CVCEs and CFCEs are tested and compared. It is found that compared with CVCEs, CFCEs can improve the focusing efficiency by about 7%, enlarge the imaging area by about 25%, and have better imaging quality at the edge of the field of view.
