    摘要： A device for authentication of a three-dimensional object includes an imaging array having a sensor configured to generate first and second sparse views of a surface of the three-dimensional object that faces the imaging array, and a processing circuitry. The processing circuitry is configured to: interpolate the first and second sparse views to obtain first and second interpolated images; calculate a planar disparity function for a plurality of image pixels of one of the first or second interpolated images; generate a projected image by displacing the plurality of image pixels of one of the first or the second interpolated images using the planar disparity function; and compare the projected image with the other of the first or second interpolated images to determine conformance of the planar disparity function with the interpolated images of the surface of the object.

    摘要： A hyperspectral imaging system and method are presented for use in reconstruction of spectral data of an object. The system comprises: a pixel matrix of a detector; a tunable dispersive unit in front of the pixel matrix; and a control system. The control system comprises: a controller for tuning the dispersive unit during n image acquisition sessions to provide n different partially overlapping spectral transmission profiles of the dispersive unit; and a control unit which is in data communication with the detector and is configured and operable for processing n image data pieces generated by the pixel matrix in said n image acquisition sessions respectively, each being indicative of a spectral image detected by the pixel matrix and corresponding to the different spectral transmission profile of the dispersive unit, and determining the reconstructed spectral data of the object.

    摘要： An apparatus (32) includes an electronic circuit (76, 80, 84), an electro-acoustic transducer (60) and a coupler (64). The electronic circuit is configured to receive data to be transmitted over an optical cable (24), and to convert the data into a modulating signal. The electro-acoustic transducer is configured to convert the modulating signal into an acoustic wave. The coupler is mechanically coupled to a section of the optical cable, and is configured to apply to the section a longitudinal strain that varies responsively to the acoustic wave, so as to modulate the data onto an optical carrier traversing the optical cable.
