    摘要： Digital cameras for spectrally imaging an object or scene comprise an imaging component, a fixed one-dimensional disperser and an image sensor having sensor pixels, the disperser and image sensor arranged with matching optical parameters and in a predetermined spatial relationship. Each sensor pixel detects multiplexed spectral information from at least two adjacent object points and the spectral information detected by each sensor pixel is demultiplexed and processed into spectral-spatial data to provide spectral images.

    摘要： Apparatus and method for obtaining a plurality of spectral images of a source object in a snapshot using comprising two-dimensional compressed sensing data cube reconstruction (2D CS-SCR) applied to a dispersed-diffused snapshot image. In some embodiments, the snapshot image is obtained through a RIP diffuser. In some embodiments, a randomizer is used to further randomized the dispersed-diffused snapshot image. The 2D CS-SCR includes applying a 2D framelet transform separately to arrays representing different wavebands of spectral cube data derived from the snapshot image. The application of the 2D framelet transform separately to the arrays representing the different wavebands includes application of direct and inverse 2D framelet transforms to the arrays. In some embodiments, the direct and inverse framelet transforms are included in a split Bregman iteration.

    摘要： A displacement sensor comprising at least one pair of co-planar photonic crystal waveguide (PCWG) sections aligned along or parallel to a common axis and separated by a gap, one PCWG section of a pair operative to perform a displacement relative to the other section of the pair. In some embodiments, the sensor is linear, comprising two PCWG sections separated by a gap that forms a cross PCWG, the displacement sensing performed preferrably differentially between two edges of the cross PCWG. In other embodiments, the sensor includes Mach Zehnder Interferometer (MZI) configurations with gaps between fixed and moving PCWG sections. Displacement induced changes in the gap widths are reflected in changes in an output parameter of the MZI.
