Abstract: A technique for automated online inspection of manufacture of a fibre reinforced polymer composite part during automated ribbon placement (e.g. ATL or AFP) uses interferometric inspection (e.g. OCT) to detect deviations from a planned lay-up for the part, to identify defects. On line, real-time inspection (i.e. on-the-fly) is demonstrated, and edge type defects and whole surface defects are identifiable. A sensor is demonstrated that does not extend a working envelope of the robotic head used for rib bon placement.

Abstract: A method for producing a multilayer tissue phantom involves successively forming at least two layers, each layer formed by depositing a viscous flowable material over a supporting element or over a previously formed layer of the phantom supported by the supporting element, selectively redistributing the material while material is solidifying to control a thickness distribution of the layer, and allowing the material to solidify sufficiently to apply a next layer. The supporting element supports the material in 2 or 3 directions and effectively molds a lumen of the tissue. The neighbouring layers are of different composition and of chosen thickness to provide desired optical properties and mechanical properties of the phantom. The phantom may have selected attenuation and backscattering properties to mimic tissues for optical coherence tomography imaging.
