Abstract: A method includes generating, by a SEM, sets of frames corresponding to regions of a microfabrication pattern, for each set of frames, estimating feature data representing edge positions, linewidths, or centerline positions of one or more features of each region of the pattern, and computing a preliminary estimate of a roughness parameter from the feature data. The roughness parameter is indicative of a line edge roughness, a linewidth roughness, or a pattern placement roughness of the one or more features. The method further includes fitting a model equation to the preliminary estimates of the roughness parameter using a model parameter dependent on the number of frames of each set of frames, the model equation relating the model parameter to the roughness parameter; and computing a final estimate of the roughness parameter as an asymptotic value of the fitted model equation.

The waveguide structure has an optical resonance spectrally overlapping a spectral absorption line or band of the species. The photoacoustic transducer includes at least one acoustic cavity formed in a portion of the waveguide structure and configured for receiving the fluid for sensing comprising the species. The at least one acoustic cavity has an acoustic resonance spectrally overlapping with a harmonic of a modulation frequency. At least one acoustic transducer comprising a deformable mechanical portion is included in the photoacoustic transducer. The deformable mechanical portion is in direct acoustic communication with the at least one acoustic cavity and has an adjustable mechanical resonance, which can be brought into spectral overlap with an acoustic resonance of the least one acoustic cavity.

Abstract: A data processing device for motion segmentation in images obtained by cameras that move in a background environment includes an input for receiving a temporal sequence of images from the cameras and a processor. The processor is adapted for, for at least two images, of the temporal sequence of images, that are obtained by at least two cameras at different points in time, determining epipoles, defining corresponding image regions of limited image disparity due to parallax around the epipoles in the at least two images, and applying a motion segmentation algorithm to the corresponding image regions. Warping is applied to the corresponding image regions to compensate for camera rotation and misalignment beyond a threshold value.

Abstract: A spectroscopic laser sensor based on hybrid III-V/IV system-on-a-chip technology. The laser sensor is configured to either (i) be used with a fiber-optic probe connected to an intravenous/intra-arterial optical catheter for direct invasive blood analyte concentration level measurement or (ii) be used to measure blood analyte concentration level non-invasively through an optical interface attached, e.g., to the skin or fingernail bed of a human. The sensor includes a III-V gain-chip, e.g., an AlGaInAsSb/GaSb based gain-chip, and a photonic integrated circuit, with laser wavelength filtering, laser wavelength tuning, laser wavelength monitoring, laser signal monitoring and signal output sections realized on a chip by combining IV-based semiconductor substrates and flip-chip AlGa1-nAsSb/GaSb based photodetectors and embedded electronics for signal processing. Embodiments of the invention may be applied for real-time monitoring of critical blood analyte concentration levels such as lactates, urea, glucose, ammonia, albumin, etc.
