The tomographic reconstruction of the refractive index distribution in a large-mode-area photonic fiber is presented. The results of the diffraction tomographic algorithm and classical filtered backprojection method are compared. Additionally, the application of the synthetic aperture technique to tomographic interferometry, as a tool for resolution enhancement, is presented and discussed.
Microinterferometric tomography method for determination of 3D refractive index distribution in phase elements is described. . Applications ofthis method to measurement of gradient index fibers, fiber splices and single mode fiber are presented. Initial results ofholey fiber testing are given and future trends in development ofthis method ( applications to photonic structures ) are discussed.
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.
