Abstract
A method and apparatus for detecting the composition of a moving web product on a real-time basis during the manufacturing process. Spectrometric monitoring equipment operates to derive information regarding physical and/or chemical properties of the web at multiple locations in the web's cross direction. Data from a plurality of spectral regions can be combined to produce a vector containing accurate information regarding the web's composition. This information is derived using multivariate mathematical techniques to yield a spatial data matrix for each component of interest. Composition information contained in the spatial data matrix can be reprojected as a “virtual composition map,” or compared against ideal profiles stored in a computer memory.
