Abstract: An optical light diffusing system is provided that includes an optical diffuser that coverts incoming light into diffused light. To prevents mixing light from undesired directions in the diffuser, light form undesired direction is baffled before it reaches the diffuser. Baffling is performed with an array of micro lenses located in the optical path to the diffuser. An array of apertures is located between the array of micro lenses and the optical diffuser. Each micro lens is aligned with a corresponding aperture. The apertures are located substantially in a focal surface of the array of micro lenses. Optical baffles located between the array of micro lenses and the array of apertures, separates optically transparent volumes between different ones of the micro lenses and their corresponding apertures.

Abstract: In accordance with an aspect of the present application, a system is provided for crack monitoring in a structure of interest, comprising means for extracting wave modes existing in a frequency interval of interest, means for finding a source of emission on the structure of interest, means for correcting for dispersion to reconstruct an original ratio of wave modes at the source of emission, and means for correlating the original ratio of wave modes to a crack depth. One advantage of this solution in contrast to prior art techniques is that no a priori knowledge on propagation speed is necessary since actual wave modes can be detected from dispersion relations of wave modes, e.g. Lamb waves at a fixed frequency band in accordance with their calculated speeds. Decentralized acquisition and processing, i.e. monitoring a structure from a localized area, is an important feature of this solution, consequent to which, the data transfer and storage are reduced substantially.

Abstract: The thickness of an at least partially transparent layer is measured using wavelength band limited light, with a coherence length that is less than twice the thickness of the layer. Reflections from layer are fed to a 2-n coupler (n>2) via optical transmission paths of different optical length. The 2-n coupler mix light from the path into n combinations of light from the paths, each combination with a different mutual phase offset between the light from the two paths. This leads to coherent interference between reflections from the front and back of the layer when the difference between the optical lengths of the optical transmission paths compensates for the path between reflection from the front and the back. A processing circuit computes information indicative of a phase difference between the reflections from n intensities of the 2-n coupler. The use of n>2 signals makes it possible to eliminate the influence of reflection amplitude variations on the computed phase difference.
