“…Organisms have evolved diverse and superior visual systems, which enable them to effectively navigate, find food, communicate and avoid predators in their complex and dangerous natural environments (Smolka et al, 2011;Lim and Ben-Yakir, 2020;Casares and McGregor, 2021). Inspired by the visual systems of biological organisms in the natural world, a wide range of artificial biomimetic visual systems has been developed in the both macroscale and microscale Wang et al, 2019;Ma et al, 2021). However, despite the significant advancements in size and weight, micro vision cameras still have some shortcomings, including low image quality, limited focal length, narrow field of view, and high precision requirements for detection.…”

As an outstanding visual system for insects and crustaceans to cope with the challenges of survival, compound eye has many unique advantages, such as wide field of view, rapid response, infinite depth of field, low aberration and fast motion capture. However, the complex composition of their optical systems also presents significant challenges for manufacturing. With the continuous development of advanced materials, complex 3D manufacturing technologies and flexible electronic detectors, various ingenious and sophisticated compound eye imaging systems have been developed. This paper provides a comprehensive review on the microfabrication technologies, photoelectric detection and functional applications of miniature artificial compound eyes. Firstly, a brief introduction to the types and structural composition of compound eyes in the natural world is provided. Secondly, the 3D forming manufacturing techniques for miniature compound eyes are discussed. Subsequently, some photodetection technologies for miniature curved compound eye imaging are introduced. Lastly, with reference to the existing prototypes of functional applications for miniature compound eyes, the future development of compound eyes is prospected.

“…The fiber bundle imaging technique has demonstrated its success in military periscope, life detection, and endoscopic imaging [1], owing to the inherent flexibility of fiber optics. By constructing a compact set of lenses, multiple low-resolution (LR) sub-images are formed in the compound eye system [2,3], and compositing sub-eye images are achieved by post-processing. In addition, combining the advantages of infrared imaging and fiber optic sensing, it can provide more valuable technical approaches to the field of detection and open up a variety of applications.…”

As the representative of flexibility in optical imaging media, in recent years, fiber bundles have emerged as a promising architecture in the development of compact visual systems. Dedicated to tackling the problems of universal honeycomb artifacts and low signal-to-noise ratio (SNR) imaging in fiber bundles, the iterative super-resolution reconstruction network based on a physical model is proposed. Under the constraint of solving the two subproblems of data fidelity and prior regular term alternately, the network can efficiently “regenerate” the lost spatial resolution with deep learning. By building and calibrating a dual-path imaging system, the real-world dataset where paired low resolution (LR) - high resolution (HR) images on the same scene can be obtained simultaneously. Numerical results on both USAF target and complex target objects demonstrate that the algorithm can restore high contrast images without pixilated noise. On the basis of super-resolution reconstruction, compound eye image composition based on fiber bundle is also realized in this paper for the actual imaging requirements. The proposed work is the first to apply a physical model-based network structure to fiber bundle imaging in the long-wave infrared band, effectively promoting the engineering application of thermal radiation detection.

“…Researchers conducted research on artificial compound eyes after being inspired by the compound eyes of animals. The resolution of the prepared compound eye imaging system has been steadily increasing as scientific cognition and processing technology [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ] advance. At the moment, artificial compound eyes are facing numerous challenges, and researchers are constantly investigating new technologies and materials in order to apply artificial compound eyes to more scenes [ 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 ] and solve problems that traditional optical systems cannot.…”

Compound eye cameras are a vital component of bionics. Compound eye lenses are currently used in light field cameras, monitoring imaging, medical endoscopes, and other fields. However, the resolution of the compound eye lens is still low at the moment, which has an impact on the application scene. Photolithography and negative pressure molding were used to create a double-glued multi-focal bionic compound eye camera in this study. The compound eye camera has 83 microlenses, with ommatidium diameters ranging from 400 μm to 660 μm, and a 92.3 degree field-of-view angle. The double-gluing structure significantly improves the optical performance of the compound eye lens, and the spatial resolution of the ommatidium is 57.00 lp mm−1. Additionally, the measurement of speed is investigated. This double-glue compound eye camera has numerous potential applications in the military, machine vision, and other fields.
