Abstract

By capturing both the two-dimensional intensity and orientation information, the light-field camera is capable of generating depth information during the refocusing process. This technology holds great potential for applications in computational photography and computer vision. According to the imaging principle of microlens array light-field camera, this paper presents a design method for an light-field camera imaging system based on a metalens array. The method encompasses the overall design of the light-field camera imaging system as well as specific design considerations for the lens unit. Simulation and design results indicate that the optical system has the capability to achieve near-diffraction-limited imaging. The metalens units, which utilize the concentric nanorings structure, not only significantly reduce computational costs but also provide excellent achromatic imaging performance across the visible spectrum.
