我们提出了一种用于实时视觉系统的超紧凑光学器件的微光学方法，其灵感来自昆虫的复眼。演示的模块实现了大约。 VGA 分辨率，总轨道长度为 1.4 毫米，比相同像素间距的图像传感器上的同类单孔径光学器件短约两倍。将不同光通道中分别记录的部分图像拼接在一起，通过图像处理形成整个视场的最终图像。对每个部分图像应用软件校正，使最终图像不失真。微透镜阵列是通过最先进的晶圆级微光学制造技术实现的，适用于大批量的潜在应用，例如：用于消费电子产品。 (C) 2010 美国光学学会
We propose a microoptical approach to ultra-compact optics for real-time vision systems that are inspired by the compound eyes of insects. The demonstrated module achieves approx. VGA resolution with a total track length of 1.4 mm which is about two times shorter than comparable single-aperture optics on images sensors of the same pixel pitch. The partial images that are separately recorded in different optical channels are stitched together to form a final image of the whole field of view by means of image processing. A software correction is applied to each partial image so that the final image is made free of distortion. The microlens arrays are realized by state of the art microoptical fabrication techniques on wafer-level which are suitable for a potential application in high volume e.g. for consumer electronic products.
