ABSTRACT:
A method and apparatus for interpreting spectral data in an optical sensor for a variety of uses, such as the manufacture of paper. A probe is inserted into paper pulp during the manufacturing process. The probe emits light into the pulp which is then reflected back and received. This reflected light is segmented into N different wavelengths over the visible spectrum. An N signal array is created which is used in a mathematical model to accurately depict a brightness and consistency of the paper pulp.
