2014 La diffraction d'une porteuse puissante qui se propage dans une chaine de communication non guidée (atmosphère sèche) est plus rigoureusement étudiée. Quatre points pertinents sont examinés i) distribution radiale de la température, ii) paramètre « largeur moyenne du faisceau », iii) facteur de mérite normalisé de distortion optique, et iv) mise en forme d'un champ optique pour réduire la diffraction créée par les effets réfractifs. Abstract 2014 This paper investigates, more rigorously, the diffraction of a powerful optical carrier propagating in an unguided communication channel (dry atmosphere). Four main relevant topics are considered i) the radial temperature distribution, ii) the average beamwidth parameter, iii) a dimensionless optical distortion figure of merit, and iv) the irradiance tailoring technique as a method to reduce the diffraction caused by refractive effects.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
