Abstract:
Systems and methods are disclosed relating to composite photonic materials used to design structures and detecting 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 measurable change in the structure's diffraction pattern. An inspection device is also provided that 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.

Claim (Index 16):
A device for non-destructive inspection of a photonic structure having a periodic refraction grating, comprising:\n a lamp configured to emit a cone of radiation toward and onto a portion of a sample, the radiation having constant intensity over a range of wavelengths; a camera sensor configured to capture an image of diffracted radiation, wherein the diffracted radiation is the radiation emitted by the lamp as diffracted by the portion of the sample, and wherein the image provides one or more wavelengths of the radiation captured at each respective point on the captured image; a computer readable storage medium including one or more software modules including an analysis module, wherein each module includes executable code; and a processor communicatively coupled to the lamp, the camera sensor and the storage medium, wherein the processor is configured by executing the code in the one or more software modules to analyze the image of the captured radiation in order to determine a displacement of any perturbations within the portion of the sample by, for each point on the captured image:\n transforming the wavelength at the point to a first periodicity value for a corresponding point within the portion of the sample as a function of a position of the lamp and the camera sensor relative to the sample and a diffraction angle for the corresponding point within the portion of the sample, and \n computing an amount of deformation for the corresponding point based on the first periodicity value and a reference periodicity; and \n a visual display in signal communication with the processor, wherein the processor is configured to output an image of the sample representing the amount of deformation computed for each corresponding point within the portion of the sample using the display.
