Our approach is similar to those used by phase diversity and multi-conjugate adaptive optics but instead uses imagery from a single light field frame. Similar to those approaches ours provides a joint estimate of both the scene and the turbulence volume. We present results featuring multiple scenes, integrated turbulence strengths, and isoplanatic angles. Light field sampling effects are also considered.","PeriodicalId":340236,"journal":{"name":"Laser Communication and Propagation through the Atmosphere and Oceans X","volume":"690 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116112855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
