Description

Technical Field

[0001] The present invention relates to the field of optical imaging technology, and in particular to an outdoor intelligent all-sky narrowband imager system. Background Art

[0002] The all-sky narrowband imager is an instrument used to observe narrowband light radiation of specific wavelengths in the atmosphere over the entire sky. It selects a spectrum with a bandwidth of 2.5nm in the range of 400nm to 900nm to perform high-sensitivity imaging of weak radiation from natural phenomena such as auroras and airglow. Auroras are luminous phenomena produced by the interaction of charged particles from the sun and the Earth's magnetosphere, while airglow is the weak light emitted after the atmosphere absorbs solar radiation. The instrument has a wide field of view and can accurately capture the radiation characteristics of narrow bands in the atmosphere. It is widely used in the study of Earth's atmospheric physics and the relationship between the Sun and the Earth's space environment.

[0003] In the actual implementation process, there are still some problems: 1. Traditional all-sky narrowband imagers cannot be installed independently outdoors and can only be installed and used indoors. At the same time, they need to use an ultra-large-aperture transparent hemispherical cover to collect all-sky images. Due to the large temperature difference between the inside of the transparent hemispherical cover and the external environment, condensation or frost is very likely to occur, resulting in poor image quality or even direct unusability, which seriously restricts the normal use and efficient operation of such equipment.

[0004] 2. Traditional all-sky narrowband imagers are typically installed indoors and observe through a large transparent hemispherical cover. This design presents multiple challenges, including bulky size and complex structure, inconvenient transportation, and demanding installation. These limitations limit the flexible deployment and rapid movement of the equipment, increasing maintenance costs and the risk of failure. Overall, traditional equipment lacks portability, high-quality imaging, and intelligent control, making it difficult to meet the demands of outdoor applications in diverse and changing environments.
