However, in the practical receiver system, reflections occurring between optical elements introduce non-normal incident components in the light beams passing through the FPI. This phenomenon results in the deformation of the FPI transmission spectral lines. Based on that, a theoretical model has been developed to describe the transmission spectrum of the FPI when subjected to obliquely incident light beams with a divergence angle. By appropriately adjusting the model parameters, the simulated transmission spectrum of the FPI edge channels can coincide with the experimentally measured FPI spectral line. Subsequently, the impact of deformations in the transmission spectrum of the two edge channels on wind measurements is evaluated. The first implication is a systematic shift of 30.7 m\/s in line-of-sight (LOS) wind velocities. This shift is based on the assumption that the lidar echo is solely backscattered from atmospheric molecules. The second consequence is the inconsistency in the response sensitivities of Doppler frequency shift between Rayleigh signals and Mie signals. As a result, the lidar system fails to fully achieve its initial design objectives, particularly in effectively suppressing interference from Mie signals. The presence of aerosols can introduce a significant error of several meters per second in the measurement of LOS wind velocity.<\/jats:p>","DOI":"10.3390\/rs16061076","type":"journal-article","created":{"date-parts":[[2024,3,19]],"date-time":"2024-03-19T09:39:31Z","timestamp":1710841171000},"page":"1076","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The Impacts of Deformed Fabry\u2013Perot Interferometer Transmission Spectrum on Wind Lidar Measurements"],"prefix":"10.3390","volume":"16","author":[{"given":"Ming","family":"Zhao","sequence":"first","affiliation":[{"name":"School of Electronic Engineering, Huainan Normal University, Huainan 232038, China"},{"name":"Key Laboratory of Atmospheric Optics, Anhui Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, Hefei 230031, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8346-1173","authenticated-orcid":false,"given":"Jianfeng","family":"Chen","sequence":"additional","affiliation":[{"name":"Key Laboratory of Atmospheric Optics, Anhui Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, Hefei 230031, China"},{"name":"Science Island Branch, University of Science and Technology of China, Hefei 230026, China"}]},{"given":"Chenbo","family":"Xie","sequence":"additional","affiliation":[{"name":"Key Laboratory of Atmospheric Optics, Anhui Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, Hefei 230031, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3918-6696","authenticated-orcid":false,"given":"Lu","family":"Li","sequence":"additional","affiliation":[{"name":"Science Island Branch, University of Science and Technology of China, Hefei 230026, China"},{"name":"Faculty of Mechanical and Automotive Engineer, West Anhui University, Lu\u2019an 237012, China"}]}],"member":"1968","published-online":{"date-parts":[[2024,3,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"8847","DOI":"10.1002\/2016JA023713","article-title":"Stratosphere and lower mesosphere wind observation and gravity wave activities of the wind field in China using a mobile Rayleigh Doppler lidar","volume":"122","author":"Zhao","year":"2017","journal-title":"J.
