“…Inspired by the structure of arthropods' compound eyes in the natural world, researchers have utilized micro-nanofabrication techniques to create optical microstructures based on planar and curved bio-inspired compound eye structures [17][18][19][20][21]. Due to the advantages of high integration, small size, large field of view imaging, and minimal impact from diffraction limits, biomimetic compound eyes find widespread applications in the military (missile guidance and radar detection), industrial (micro cameras and robot vision), and clinical medical (endoscopy) fields [22][23][24][25][26][27][28][29][30][31][32][33][34].…”

Over millions of years of evolution, arthropods have intricately developed and fine-tuned their highly sophisticated compound eye visual systems, serving as a valuable source of inspiration for human emulation and tracking. Femtosecond laser processing technology has attracted attention for its excellent precision, programmable design capabilities, and advanced three-dimensional processing characteristics, especially in the production of artificial bionic compound eye structures, showing unparalleled advantages. This comprehensive review initiates with a succinct introduction to the operational principles of biological compound eyes, providing essential context for the design of biomimetic counterparts. It subsequently offers a concise overview of crucial manufacturing methods for biomimetic compound eye structures. In addition, the application of femtosecond laser technology in the production of biomimetic compound eyes is also briefly introduced. The review concludes by highlighting the current challenges and presenting a forward-looking perspective on the future of this evolving field.

In this work, we demonstrated a new type of biomimetic multispectral curved compound eye camera (BM3C) inspired by insect compound eyes for aerial multispectral imaging in a large field of view. The proposed system exhibits a maximum field of view (FOV) of 120 degrees and seven-waveband multispectral images ranging from visible to near-infrared wavelengths. Pinhole imaging theory and the image registration method from feature detection are used to reconstruct the multispectral 3D data cube. An airborne imaging experiment is performed by assembling the BM3C on an unmanned aerial vehicle (UAV). As a result, radiation intensity curves of several objects are successfully obtained, and a land type classification is performed using the K-means method based on the aerial image as well. The developed BM3C is proven to have the capability for large FOV aerial multispectral imaging and shows great potential applications for distant detecting based on aerial imaging.

“…The planar microlens array, which is based on compound eyes with the advantages of small size and light weight, has been used to design the compact imaging system that has been used in medical imaging, safety devices, consumer applications and so on [1][2][3][4][5]. Compared to single-aperture lens system, planar microlens array has more advantages in minimizing the imaging system, so that more and more scholars have studied in its working principle and structure of thin wafer-level camera [6][7][8][9][10][11].…”
