1. one kind is configured to analyze the equipment (1) that is positioned at the article that the paper that reads volume or cardboard process, and this equipment comprises:

  • Be configured to utilize the scanner of relevant elongate light beam (15) scan articles with elongated focus, this scanner is configured to along perpendicular to the linear scan articles of the direction of the main shaft of elongated focus;

    Detector means (16);

    This detector means comprises a plurality of detecting devices;

    Each detecting device can receive the light signal of scattering on the bigger zone of the excitation area that provides than said relevant elongate light beam;

    And each detecting device is configured to detect the light signal from the roughly the same position scattering of reading volume;

    This detector means be configured to from when relevant elongate light beam from reading one group of data point of signal collection that the volume reflex time obtains, wherein said data point is with relevant from the scattering of the different piece that reads volume, and the signal correction of different data points and the different moment acquisitions of scan period;

    AndData obtain and processing module (36), are configured to handle said one group of data point, whether have the intrinsic surface structure that produces the class signature of being scheduled to confirm article, and said predetermined class signature is discerned the article of known genera class from the intrinsic surface texture properties of article.
