“…Завдяки нахилу груп оптичних волокон можна забезпечити велике поле зору. Інший варіант такої ФСТЗ представляє собою комбінацію цифрової камери та оптичного компонента, який розширює поле зору за допомогою оптичних волокон, які з однієї сторони закріплені на сферичній поверхні, а з іншої -на плоскій поверхні, що розташована у площині предмета цифрової камери [47] (Рисунок 12). Такі системи мають такі самі переваги та недоліки як будь-які ФСТЗ з матричними фотоприймачами, а оптичні волокна у них використовуються лише для розширення поля зору.…”

The article proposes a classification of facet systems of technical vision. According to this classification, all systems are divided into groups depending on the type of optical system, which can be represented as a combination of microlenses, optical fibers and an objective, and the type of photoreceptors - matrix, linear or single-element photoreceptor. The construction of facet systems was considered, an analysis of their advantages and disadvantages was performed, recommendations were formulated regarding the choice of a facet system of technical vision.

“…Ma et al fabricated an optical fiber compound eye for detecting the orientation of objects (Figure 14a). [156] Figure 14b shows the calibration system which consisted of a fiber compound eye, LED target, a camera, a position support device, and a turntable. When the calibration was completed, the neural work was used to predict the accuracy of the system.…”

the visual nerve perception. This type of eyes has ultrahigh resolution, which can get clear image information. Inspired by this imaging system, people have put significant efforts over a long time for development of camera-related optical system for various applications, such as endoscope, digital camera, smartphones, robot eyes, visual implants. [7][8][9][10] Because of the rapid progress in micro/nano technologies, the artificial eyes structures can achieve extremely high resolution that is close to or even exceeding the human eye. However, the low field of view (FOV) (the maximum value is only 90°) hinders its wider applications. To solve this problem, multiple cameras need to be put together to work, which not only increases the cost, but also makes the entire optical system cumbersome. Hence, an optical device with portable, integrated, and large FOV features is highly desired.Different from the single-lens eyes, the insect eyes adopt another visual system. Figure 1b shows a honeybee's apposition compound eye, which has thousands of ommatidia arranged on a curved surface so that each ommatidium points in different directions. [11] Each unit consists of a lens, a crystalline cone, and a rhabdom. The focused light signal is transmitted to the photosensitive area by the crystalline cone, and then visual perception is generated after passing through the rhabdom. Each of the ommatidium can image which enables the insects to obtain sufficient information in a complex environment and exhibits the characteristics of large FOV, low aberration, and high sensitivity to moving objects. [12] In addition to the honeybee's compound eyes, the eyes of other insects in nature, such as mosquito eye, [13] fly's eye, [14] moth's eye, [15] and dragonfly's eye [16] also have similar structure and have attracted much attention due to the deep research on bionics. [4,9,12,[17][18][19][20][21] The characteristics of the compound eyes in nature and the advanced micro/nano-processing technologies provide great technical support and inspiration for the researchers to prepare artificial compound eyes (ACEs) with close-packed microlens arrays (MLAs) as optical imaging elements. [22][23][24][25][26][27][28][29][30] Such MLAs compose of microscale lenses with the same surface feature and the regular arrangements are important microoptical components. The great light field (LF) regulation and focusing abilities of MLAs have made it essentially in various applications such as imaging, [31][32][33][34][35][36][37][38][39] dynamic target capture, [40][41][42] beaming homogenizing, [43][44][45][46] sensing, [47][48][49] light extractionThe natural compound eyes provide great inspiration for design of advanced imaging devices. Artificial compound eyes (ACEs) with close-packed microlens arrays (MLAs) have attracted enormous research interests due to their remarkable advantages in modern micro-optical systems, such as miniaturization, high integration, tunable focal length, large field of view, and moving objects tracking. Over a decade of intens...

“…In addition, compound eyes as a common organ have been seen with symmetric honeycomb micro-lens arrays in many insects, such as flies and moths. 6 These highly ordered arrays efficiently manage the direction of light propagation to collect more light from a narrow incident angle range and enlarge the view angle for fast detection during movement. 7 Therefore, bioinspired honeycomb structures have been applied in the fields of solar cells, optical devices, precision sensors, and so on.…”
