Method and apparatus for controlling a cellulosic pulp process

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 inwavelength 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. 本发明公开了种用于控制生产具有所需纸浆性质的纸浆产品的纤维素纸浆加工的方法和装置。该方法包括使用第波长的光照射纸浆的加工中部分，并从被照射的纸浆部分接收散射光谱，所述散射光谱包括通过与被照射的纸浆部分的组分相互作用而波长偏移的光谱分量。该方
