  • Patent number: 10450700
    Abstract: A method and apparatus for controlling a cellulosic pulp process for producing a pulp product having a desired pulp property is disclosed. The method involves illuminating an in-process portion of pulp using a first wavelength of light, and receiving a scattered light spectrum from the illuminated portion of pulp, the scattered light spectrum including spectral components that have been shifted in wavelength through interaction with a constituent of the illuminated portion of pulp. The method also involves filtering the scattered light spectrum to separate the spectral components, and identifying spectral features in the filtered scattered light spectrum that correspond to the pulp property. The method further involves generating a control signal for controlling the pulp process based on variations in the identified spectral features to cause the pulp property to fall within a desired range.
