    Abstract: A method for identifying carpet materials includes receiving, by a controller coupled to an NIR spectrometer, a predetermined number of NIR measurements of a sample of the carpet material conducted over a bandwidth of a subset of a full NIR spectrum. The NIR spectrometer performs the NIR measurements under control of the controller. Also, sending the NTR measurements to a remote identification server including a spectra library of known carpet materials. The method also includes receiving a matching result from the remote identification server, sending the matching result to a remote appraisal server, and receiving an appraised value of the carpet material.

    Abstract: An apparatus for determining fiber orientation parameters of a sheet of material during a production process includes a polarized radiation generating system operable for providing polarized radiation having a frequency of at least 1×108 Hz. The radiation is aligned to be incident on a sheet material to be characterized. A polarimeter is aligned to receive the radiation transmitted by the sheet material. A photodetector is provided for measuring radiation received after polarization processing by the polarimeter. A processor is coupled to the photodetector for calculating Stokes parameters of the sheet material based upon intensities of the radiation received and determines at least one parameter relating to fiber orientation of the sheet material based upon the Stokes parameters.
