  • Methods and apparatus for automated product identification in point of sale applications
    Patent number: 8113427
    Abstract: Systems and techniques for product identification using terahertz radiation detection. An area of interest is illuminated with radiation in the terahertz frequency range and terahertz radiation reflected from objects within the area of interest is detected and a detector signal based on the detected radiation is processed to generate identifying information for the objects. The generated identifying information may be compared against stored identifying information for products and the result of the comparison is used to select a product or group of products for which the comparison produces a match. Processing of the detector signal may generate a spectral signature characteristic of reflective and absorptive properties of an object under illumination, and the spectral signature may be compared with stored spectral signature information for products.
