Abstract

This paper reports the development of a miniature optoelectronic integrated compound eye camera. The camera uses polymer compound eyes with 19-160 logarithmic profile ommatidia, fabricated via femtosecond laser two-photon polymerization. This design addresses defocusing problems associated with spherical ommatidia, enabling direct integration with a commercial CMOS detector. The resulting camera achieves a 90° field-of-view, spatial position identification, and sensitive trajectory monitoring. It can also be integrated with a microfluidic chip for real-time monitoring of microorganisms. This insect-scale camera provides a practical method for integrating planar imaging sensors with complex micro-optics.
