The aim of this paper is to discuss the possibility of a noninvasive, optical characterization of a transparent (glass) fiber on the basis of scattered light in the vicinity of a primary rainbow. Computational studies show that with the use of a spectrally adjusted incident beam of light, it is possible to form a rainbow with no strong nonlinearities typical for coherent light and that may be interpreted in terms of Airy's theory of rainbow. An inverse analysis is applied to obtain the fiber diameter with the help of a straightforward mathematical formula based on the Airy integral, corrected by comparison with the solution according to the complex angular momentum method.
One of the most promising and innovative developments in medicine are telemedical systems. The system PulmoTel 2010 and its internal validation are presented, focusing on the system architecture, hardware, software and communication solutions. PulmoTel 2010 consists of a distant server managing users and medical devices, as well as data transmission, processing, storage and presentation. The server cooperates with home units used by patients, capable of performing lung function tests. All the elements communicate via the Internet, however other media, as wire and mobile telephony, can be additionally applied in regions with a less developed infrastructure. Internal validation of the system was performed using data generated by application simulating features of a home unit. It demonstrated an appropriate operation of the overall system and fulfillment of the main objectives of the project.
The objective of this paper is to discuss the possibility of noninvasive optical characterization of a transparent (glass) fiber by means of low-coherent light scattering. It will be shown that, by adjusting the temporal coherence of incident light, it is possible to select these specific orders of scattering, which are related to diffraction. Discussion will be devoted to the direct scattering and the inverse problem, where an inference about the diameter of a multilayered and transparent fiber is accomplished.
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.
