Spectroscopy, especially imaging spectroscopy that takes advantage of angular resolution approaching the diffraction limit of the primary mirror, is treated as an add‐on, rather than an integral component in these telescope designs. Studies of specific complex objects whether they be a galaxy, stars ...
我很好奇 VIS 到底什么的缩写?另外就是为何在图像识别中非要强调 VIS image? UV / VIS / NIR UV: ultra-violet,紫外线。或,紫外可见吸收光谱(Ultraviolet and Visible Spectrum),简写为UV。 VIS: visible,可见 NIR: near infra-red,近红外 红外线和紫外线都是我们日常生活中经常接触的光线,绝大部分的红外线...

Ultraviolet and visible spectroscopy deals with the recording of the absorption of radiations in the ultraviolet and visible regions of the electromagnetic spectrum. The ultaviolet region extends from 10 to 400 nm. It is subdivided into the near ultraviolet (quartz) region (200–400 nm) and the...
Ultraviolet (UV)–visible spectroscopy is a spectrophotometric technique employed to measure photons of light within the UV–visible region, measuring the intensity of light before and after it passes through the material. From: Antibiotic Materials in Healthcare, 2020 ...
