An artificial compound-eye objective fabricated by micro-optics technology is adapted and attached to a CMOS sensor array. The novel optical sensor system with an optics thickness of only 0.2 mm is examined with respect to resolution and sensitivity. An optical resolution of 60 x 60 pixels is determined from captured images. The scaling behavior of artificial compound-eye imaging systems is analyzed. Cross talk between channels fabricated by different technologies is evaluated, and the influence on an extension of the field of view by addition of a (Fresnel) diverging lens is discussed. The lithographic generation of opaque walls between channels for optical isolation is experimentally demonstrated.
通过微光学技术制造的人工复眼物镜被适配并附着到CMOS传感器阵列上。对这种光学厚度仅为0.2毫米的新型光学传感器系统的分辨率和灵敏度进行了研究。从捕获的图像中确定了60×60像素的光学分辨率。分析了人工复眼成像系统的缩放行为。评估了不同技术制造的通道之间的串扰，并讨论了添加（菲涅耳）发散透镜对扩展视野的影响。通过实验证明了用于光学隔离的通道之间不透明壁的光刻生成。
