Jumper","doi":"10.1109/PHOSST.2012.6280755","DOIUrl":"https://doi.org/10.1109/PHOSST.2012.6280755","url":null,"abstract":"When a laser beam is transmitted from an airborne platform, it must first pass through a relatively thin region of the turbulent flow in the immediate vicinity of the airplane. Unsteady density variations present in the turbulent flow will imprint spatial/temporal variations on the otherwise planar outgoing wavefronts. These variations in wavefronts will force the beam to move, change its shape and even break into several spots on a distant target. These aero-optical effects [1,2], even in the absence of any atmospheric optical distortions, might significantly degrade a performance of any free-space, laser-based airborne systems at subsonic, transonic or supersonic speeds.","PeriodicalId":275054,"journal":{"name":"2012 IEEE Photonics Society Summer Topical Meeting Series","volume":"307 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122733815","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}
