Abstract: Spectrometer designs are provided. The spectrometer includes two planar diffraction gratings disposed in a cascade, without intervening optics therebetween. Advantageously, the described configurations may promote both a high throughput and a high resolution, enabling the design of a portable device having sufficient resolution for on-site use or in the laboratory. In some implementations, two different secondary diffraction channels may be provided.

Abstract: A LIBS system to detect constituent elements of interest within a sample from plasma light resulting from irradiation of this sample is presented. The LIBS system has a hybrid configuration which provides both a low-resolution spectrum of the plasma light covering a broad spectral range, and a high-resolution spectrum of the same plasma light over a narrow spectral range centered on a spectral line or feature of a constituent element of interest of the sample. In some implementations, the LIBS system has a portable design and can perform onsite sample analyses.

Abstract: Described are various embodiments of a system, method and device for laser induced breakdown spectroscopy (LIBS). In some embodiments, the LIBS system comprises a silicon photomultiplier (Si PM) operated in a time-gated photon counting mode. Some such embodiments allow for the provision of a portable LIBS device. Also provided are embodiments for the measurement of constituent carbon, gold and/or other precious metal group elements in a target sample.

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 ribbon placement.
