Nettet14. apr. 2024 · Background. This study reports the results of a set of discrimination experiments using simulated images that represent the appearance of subtle lesions in low-dose computed tomography (CT) of the lungs. Noise in these images has a characteristic ramp-spectrum before apodization by noise control filters. We consider … NettetThe Journal of the Optical Society of America B (JOSA B) is a general optics research journal that complements JOSA A. It emphasizes research on the fundamentals of the …

Nettet5. apr. 2024 · In this Roadmap an overview is given about the most recent experimental and computational results obtained within the Italian research community on the optimization of composition and morphology of some thermoelectric materials, as well as on the design of thermoelectric and hybrid thermoelectric/photovoltaic devices. NettetThe controversial term “nondiffracting beam” was introduced into optics by Durnin in 1987. Discussions related to that term revived interest in problems of the light diffraction and resulted in an appearance of the new research direction of the classical optics, dealing with the localized transfer of electromagnetic energy. In this paper, the physical concept of … NettetE. Yablonovitch, “Photonic band gap structures,” J. Opt. Soc. Am. 10 (283–295) 1993. Google Scholar Special issue of J.
