Capsule endoscopes are pill-sized devices that physicians can utilize for diagnosis of a patient’s small intestine. For diagnostic requirements, excellent image quality, large field of view (FOV) and compact size are crucial. In this paper, a multi-camera capsule endoscope (MCCE) composed of two wafer level optic modules and microprism elements which can offer both a large FOV and clear image quality within limited space conditions is described. The properties of the microprism needed to ensure the necessary image quality are further discussed, including working efficiency, the ability to increase the FOV, and the inhibition of chromatic aberration. Finally, the functioning of the MCCE is verified through an optical simulation and preliminary experiments. The results show that the max half FOV of the MCCE could be increased from 28° to 37°, and the relative illumination could be kept at 80% without a dark corner effect.

“…Ferrato [14] presented a microscope design for multiband chromatic aberration correction. Sun et al [15] proposed a new method for the 2 of 13 optimization and correction of chromatic aberration with double prisms, and applied it to a stereo photographic system with achromatic double prism arrays [16] and a doublet lens [17]. In 2010, Sun [18] proposed an illustrating method for a triplet prism combination for minimizing the chromatic aberration.…”

“…In our previous publication [15], the triple prisms can be incorporated to correct the chromatic aberration for a thin triplet lens design by increasing the thickness of the thick lens and the spacing between the lenses while maintaining the focal length of the triplet lens. To correct for the increased chromatic aberration caused by the lens thickening, we used an optimization algorithm combined with an illustration method to ensure that the chromatic aberration of the thickened triplet lens system is close to that of a thin lens system.…”

This paper proposes an optimization algorithm combined with an illustration method to select the three best glass materials for the design of a thickened triplet lens and a correction of the paraxial chromatic aberrations. In the thin lens thickening process, chromatic aberration arises from the deviation between the real and paraxial chromatic aberrations. To solve this problem, we propose an optimization algorithm and illustration method, which are integrated into a thickened triplet lens design. We optimize the eight thickened triplet lens groups to obtain the longitudinal chromatic aberration curve for the best group in the visible light range from 0.4861 μm to 0.6563 μm. The chromatic aberration curve area is 3.33 × 10−7 (μm × mm) for the longitudinal chromatic aberration and 2.11 × 10−5 (μm × mm) for the lateral chromatic aberration. Finally, the chromatic aberration of the thicken triplet lens is close to that of the thin triplet lens design, and the proposed method can obtain a good optical performance.

Diffractive optical elements (DOEs) represent a revolutionary advancement in modern optics, offering unparalleled versatility and efficiency in various applications. Their significance lies in their ability to manipulate light waves with intricate patterns, enabling functionalities beyond what traditional refractive optics can achieve. DOEs find widespread use in fields such as laser beam shaping, holography, optical communications, and imaging systems. By precisely controlling the phase and amplitude of light, DOEs can generate complex optical structures, correct aberrations, and enhance the performance of optical systems. Moreover, their compact size, lightweight nature, and potential for mass production make them indispensable in designing compact and efficient optical devices for diverse industrial and scientific applications. From improving the performance of laser systems to enabling innovative display technologies, DOEs continue to drive advancements in modern optics, promising even more exciting possibilities in the future. In this review, the critical importance of DOEs is illuminated and explore their profound implications in the contemporary era.
