All-sky cameras capture a panoramic view of the full sky from horizon to horizon to generate a wide-angle image of the observable sky. State-of-the-art all-sky imagers are limited to imaging in the visible and infrared spectrum and cannot image in the UV spectrum. This article describes the development of an all-sky imaging system capable of capturing 130° wide-angle sky images from horizon to horizon in the UV-AB spectrum. The design of the UV all-sky imaging system is based on low-cost, accessible, and scalable components to develop multiple images that can be deployed over a wider geographical area. The spectral response of the camera system has been validated in the UV spectrum (280-420 nm) using a monochromatic UV beam with an average power output of 22 nW. UV all-sky imaging systems complement existing infrared and visible all-sky cameras. They have wide applications in astronomy, meteorology, atmospheric science, vulcanology, meteors and auroral monitoring, and the defence sector.
全天空相机可以捕捉从地平线到地平线的整个天空的全景，以生成可观测天空的广角图像。最先进的全天空成像仪仅限于在可见光和红外光谱中成像，无法在紫外光谱中成像。本文描述了一种全天空成像系统的开发，该系统能够在紫外AB光谱中捕捉从地平线到地平线的130°广角天空图像。紫外全天空成像系统的设计基于低成本、易于获取且可扩展的组件，以开发能够部署在更广泛地理区域的多幅图像。该相机系统的光谱响应已在紫外光谱（280 - 420纳米）中使用平均功率输出为22纳瓦的单色紫外光束进行了验证。紫外全天空成像系统补充了现有的红外和可见光全天空相机。它们在天文学、气象学、大气科学、火山学、流星和极光监测以及国防领域有着广泛的应用。
