The first part discusses the transition from Maxwell‘s equations to ray optics. The second part establishes a general mathematical framework for treating ray optics as a theory in its own right, making extensive use of the Hamiltonian formalism. This part also includes a detailed discussion of variational principles (i.e., various versions of Fermat‘s principle) for light rays in general-relativistic media. Some applications, e.g. to gravitational lensing, are worked out. The reader is assumed to have some basic knowledge of general relativity and some familiarity with differential geometry. Some of the results are published here for the first time, e.g. a general-relativistic version of Fermat‘s principle for light rays in a medium that has to satisfy some regularity condition only. | | 出版日期 | Book 2000 | | 关键词 | EFE; Fermat‘s Principle; Graviational Lensing; Gravity; Hamiltonian Dynamics; Optics; Ray Optics; Redshift | | 版次 | 1 | | doi | https://doi.org/10.1007/3-540-46662-2 | | isbn_softcover | 978-3-642-08616-8 | | isbn_ebook | 978-3-540-46662-8Series ISSN 0940-7677 | | issn_series | 0940-7677 | | copyright | Springer-Verlag Berlin Heidelberg 2000 |
