(57) : Systems and methods are disclosed relating to composite photonic materials used to design structures and detect ma - IN terial deformation for the purpose of monitoring structural health of physical structures. According to one aspect, a composite struc - C tune is provided that includes a base material, an optical diffraction grating and one or more fluorophore materials constructed such N that localized perturbations create a measureable change in the structure's diffraction pattern. An inspection device is also provided 0 which is configured to detect perturbations in the composite structure. The inspection device is configured to emit an inspecting ra- ,1 . diation into the structure and capture the refracted radiation and measure the change in the diffraction pattern and quantify the per - .,- turbation based on the wavelength and the angular information for the diffracted radiation.
