Abstract

Multispectral imaging technology plays an important role in lots of domains, but traditional systems are limited by large volumes and complex constructions. Here, we propose a high-efficiency multispectral integrated imaging system based on metasurfaces, with its spectral range covering two important infrared windows of 3-5 μm and 8-12 μm. This system is composed of the microlens, metasurface, and filter array, hence its volume, weight, and complexity can be greatly decreased. The average efficiencies of the aforementioned two bands are over 96.47% and 97.43%, respectively. The bandwidth of each spectral channel can be tuned flexibly according to realistic requirements, which makes the system more applicable to various circumstances. The proposed design method is universally applicable and has potential applications in many aspects, such as remote sensing, epidemic monitoring, and archeology.
