Abstract:
L’imagerie directe des exoplanètes reste difficile en raison du contraste élevé et de la faible séparation angulaire entre l'étoile et la planète. Cela nécessite de supprimer l'éblouissement dû à l'étoile et de s'assurer que la lumière faible de la planète n'est pas noyée au milieu de divers bruits. La détection dépend de la maturité des techniques et des algorithmes utilisés, tout en tenant compte des compromis importants sur le contraste brut, la résolution angulaire et la transmission.

Abstract:
The polarization properties of embedded centro-symmetric and periodic multilayer stacks under conditions of frustrated total internal reflection (FTIR) are considered. The centro-symmetric multilayer stack consists of a high-index center layer sandwiched between two identical low-index films and high-index – low-index bilayers repeated on both sides of the central trilayer maintaining the symmetry of the entire stack. The periodic multilayer consists of periodically repeated low-index – high-index bilayers. Each multilayer stack is embedded in a high-index prism. Embedded centro-symmetric mult

Este trabalho teve por objetivo desenvolver e caracterizar um sensor de força utilizando uma fibra óptica modificada pelo processo conhecido como Fiber tapering. A fibra quando modificada deixa exposto o campo evanescente, o que a torna sensível a influências externas, e a luz guiada na fibra pode vir a sofrer reflexão interna total frustrada ao entrar em contato com materiais. Ao envolver a região modificada por um material elastomérico, a área de contato e consequentemente a atenuação torna-se uma função da intensidade da força aplicada, possibilitando então relacionar a força a atenuação da
