However, many factors deteriorate the performance and push it far from the shot-noise limited theoretical sensitivity. This paper reviews the mechanisms of various noises and their corresponding suppression methods in resonator-integrated optical gyroscopes, including the backscattering, the back-reflection, the polarization error, the Kerr effect, and the laser frequency noise. Several main noise suppression methods are comprehensively expounded through inductive comparison and reasonable collation. The new noise suppression technology and digital signal processing system are also addressed.<\/jats:p>","DOI":"10.3390\/s22082889","type":"journal-article","created":{"date-parts":[[2022,4,9]],"date-time":"2022-04-09T05:13:08Z","timestamp":1649481188000},"page":"2889","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Suppression Method of Optical Noises in Resonator-Integrated Optic Gyroscopes"],"prefix":"10.3390","volume":"22","author":[{"given":"Xuebao","family":"Kuai","sequence":"first","affiliation":[{"name":"School of Microelectronics, University of Science and Technology of China, Hefei 230026, China"},{"name":"Center of Materials Science and Optoelectronics Engineering, University of Chinese Academy of Sciences, Beijing 100049, China"},{"name":"Engineering Research Center for Semiconductor Integrated Technology, Institute of Semiconductors, Chinese Academy of Sciences, Beijing 100083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7285-7589","authenticated-orcid":false,"given":"Lei","family":"Wei","sequence":"additional","affiliation":[{"name":"Center of Materials Science and Optoelectronics Engineering, University of Chinese Academy of Sciences, Beijing 100049, China"},{"name":"Engineering Research Center for Semiconductor Integrated Technology, Institute of Semiconductors, Chinese Academy of Sciences, Beijing 100083, China"},{"name":"School of Microelectronics, University of Chinese Academy of Sciences, Beijing 100049, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fuhua","family":"Yang","sequence":"additional","affiliation":[{"name":"Center of Materials Science and Optoelectronics Engineering, University of Chinese Academy of Sciences, Beijing 100049, China"},{"name":"Engineering Research Center for Semiconductor Integrated Technology, Institute of Semiconductors, Chinese Academy of Sciences, Beijing 100083, China"},{"name":"Beijing Academy of Quantum Information Science, Beijing 100193, China"},{"name":"Beijing Engineering Research Center of Semiconductor Micro-Nano Integrated Technology, Beijing 100083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei","family":"Yan","sequence":"additional","affiliation":[{"name":"Engineering Research Center for Semiconductor Integrated Technology, Institute of Semiconductors, Chinese Academy of Sciences, Beijing 100083, China"},{"name":"School of Microelectronics, University of Chinese Academy of Sciences, Beijing 100049, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5986-6456","authenticated-orcid":false,"given":"Zhaofeng","family":"Li","sequence":"additional","affiliation":[{"name":"Center of Materials Science and Optoelectronics Engineering, University of Chinese Academy of Sciences, Beijing 100049, China"},{"name":"Engineering Research Center for Semiconductor Integrated Technology, Institute of Semiconductors, Chinese Academy of Sciences, Beijing 100083, China"},{"name":"School of Microelectronics, University of Chinese Academy of Sciences, Beijing 100049, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0426-1358","authenticated-orcid":false,"given":"Xiaodong","family":"Wang","sequence":"additional","affiliation":[{"name":"Center of Materials Science and Optoelectronics Engineering, University of Chinese Academy of Sciences, Beijing 100049, China"},{"name":"Engineering Research Center for Semiconductor Integrated Technology, Institute of Semiconductors, Chinese Academy of Sciences, Beijing 100083, China"},{"name":"School of Microelectronics, University of Chinese Academy of Sciences, Beijing 100049, China"},{"name":"Beijing Academy of Quantum Information Science, Beijing 100193, China"},{"name":"Beijing Engineering Research Center of Semiconductor Micro-Nano Integrated Technology, Beijing 100083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,4,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Ostrowsky, D.B., and Spitz, E.
