Lidar technology has already been proven to be effective positive remote sensing technology to construct high-resolution bathymetry models. Lidar technology significantly improves our ability to model biogeochemical processes in the upper ocean and provides advanced concepts regarding the vertical distribution of suspended particles and oceanic optical properties. In this paper, we present a novel optical approach to measuring the scattering intensity and characteristics of suspended particles within small angles backwards and distinguish water medium with different attenuation coefficients by a laboratory demonstration of the ocean Scheimpflug lidar system. The approach allows the direct determination of the scattering intensity over a small angle at the backward direction (175.8~178.8\u00b0) with an angular resolution of 0.38. Corrections for the effects of refraction at the air-glass-water interface were demonstrated. The data production (initial width and width attenuation rate of the laser beam) of the ocean Scheimpflug lidar system were utilized to distinguish water with different algae concentrations. Application for the measurement of backward scattering intensity and laser beam width were explored in distances up to several meters with spatial resolutions of millimeter precision.<\/jats:p>","DOI":"10.3390\/rs13122390","type":"journal-article","created":{"date-parts":[[2021,6,18]],"date-time":"2021-06-18T11:19:20Z","timestamp":1624015160000},"page":"2390","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Small Angle Scattering Intensity Measurement by an Improved Ocean Scheimpflug Lidar System"],"prefix":"10.3390","volume":"13","author":[{"given":"Hongwei","family":"Zhang","sequence":"first","affiliation":[{"name":"Department of Marine Technology, College of Information Science and Engineering, Ocean University of China, Qingdao 266100, China"}]},{"given":"Yuanshuai","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Marine Technology, College of Information Science and Engineering, Ocean University of China, Qingdao 266100, China"}]},{"given":"Ziwang","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Marine Technology, College of Information Science and Engineering, Ocean University of China, Qingdao 266100, China"}]},{"given":"Bingyi","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Marine Technology, College of Information Science and Engineering, Ocean University of China, Qingdao 266100, China"},{"name":"Laboratory for Regional Oceanography and Numerical Modeling, Pilot National Laboratory for Marine Science and Technology (Qingdao), Qingdao 266200, China"}]},{"given":"Bin","family":"Yin","sequence":"additional","affiliation":[{"name":"Department of Marine Technology, College of Information Science and Engineering, Ocean University of China, Qingdao 266100, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7469-1452","authenticated-orcid":false,"given":"Songhua","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Marine Technology, College of Information Science and Engineering, Ocean University of China, Qingdao 266100, China"},{"name":"Laboratory for Regional Oceanography and Numerical Modeling, Pilot National Laboratory for Marine Science and Technology (Qingdao), Qingdao 266200, China"},{"name":"Institute for Advanced Ocean Study, Ocean University of China, Qingdao 266100, China"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Soomets, T., Uudeberg, K., Jakovels, D., Brauns, A., Zagars, M., and Kutser, T.
