Here, we theoretically and experimentally investigate the UV scattering on SO2 concentration inversion. The radiation transfer model of the light dilution effect is reconstructed, and the concept of the optimized detection limit is discussed. An outfield experiment is conducted on a ship exhaust, and the results are compared with the theoretical calculations, which indicates that the detection limit of the SO2 UV camera is 15 ppm\u00b7m at close range and increases to 25 ppm\u00b7m when the detection distance is 3.5 km. This study proves that the detection limit of the SO2 UV camera deteriorates with the decreasing atmospheric visibility, the lengthening detection distance, and the increasing aerosol content within the plume. In addition, the hardware indicators of the camera systems also play a key role in the detection limit, and taking reasonable image processing can significantly release the instruments\u2019 performance and extend the applicability of the SO2 UV camera.<\/jats:p>","DOI":"10.3390\/rs15030705","type":"journal-article","created":{"date-parts":[[2023,1,26]],"date-time":"2023-01-26T02:29:31Z","timestamp":1674700171000},"page":"705","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Effect of UV Scattering on Detection Limit of SO2 Cameras"],"prefix":"10.3390","volume":"15","author":[{"given":"Kuijun","family":"Wu","sequence":"first","affiliation":[{"name":"School of Physics and Electronic Information, Yantai University, Yantai 264005, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zihao","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Physics and Electronic Information, Yantai University, Yantai 264005, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jianjun","family":"Guo","sequence":"additional","affiliation":[{"name":"School of Physics and Electronic Information, Yantai University, Yantai 264005, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiangrui","family":"Hu","sequence":"additional","affiliation":[{"name":"School of Physics and Electronic Information, Yantai University, Yantai 264005, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan","family":"Li","sequence":"additional","affiliation":[{"name":"Key Laboratory of Spectral Imaging Technology of Chinese Academy of Sciences, Xi\u2019an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences, Xi\u2019an 710119, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Faquan","family":"Li","sequence":"additional","affiliation":[{"name":"Innovation Academy for Precision Measurement Science and Technology, Chinese Academy of Sciences, Wuhan 430071, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Weiwei","family":"He","sequence":"additional","affiliation":[{"name":"School of Physics and Electronic Information, Yantai University, Yantai 264005, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"32296","DOI":"10.1364\/OE.437693","article-title":"Fiber-enhanced Raman spectroscopy for highly sensitive H2 and SO2 sensing with a hollow-core anti-resonant fiber","volume":"29","author":"Wang","year":"2021","journal-title":"Opt.
