Title (EN) SYSTEMS AND METHODS FOR CONSTRUCTING AND TESTING COMPOSITE PHOTONIC STRUCTURES
(FR) SYSTÈMES ET PROCÉDÉS POUR CONSTRUIRE ET TESTER DES STRUCTURES PHOTONIQUES COMPOSITES
Abstract: front page image
(EN)Systems and methods are disclosed relating to composite photonic materials used to design structures and detect material deformation for the purpose of monitoring structural health of physical structures. According to one aspect, a composite structure is provided that includes a base material, an optical diffraction grating and one or more fluorophore materials constructed such that localized perturbations create a measureable change in the structure's diffraction pattern. An inspection device is also provided which is configured to detect perturbations in the composite structure. The inspection device is configured to emit an inspecting radiation into the structure and capture the refracted radiation and measure the change in the diffraction pattern and quantify the perturbation based on the wavelength and the angular information for the diffracted radiation.
(FR)L'invention concerne des systèmes et des procédés relatifs à des matériaux photoniques composites utilisés pour concevoir des structures et détecter une déformation de matériau dans le but de surveiller l'état structurel de structures physiques. Selon un aspect, l'invention concerne une structure composite qui comprend un matériau de base, un réseau de diffraction optique et un ou plusieurs matériaux fluorophores construits de telle sorte que des perturbations localisées créent un changement mesurable dans le modèle de diffraction de la structure. L'invention concerne également un dispositif d'inspection qui est configuré pour détecter des perturbations dans la structure composite. Le dispositif d'inspection est configuré pour émettre un rayonnement d'inspection dans la structure et capturer le rayonnement réfracté et mesurer le changement dans le motif de diffraction et quantifier la perturbation sur la base de la longueur d'onde et des informations angulaires pour le rayonnement diffracté.
