Literature Cited

The measuring principle of this method is optical and is based on the ability of the fiber to change the direction of light polarization.

Describes an automated method by which the numerical and weighted average fiber lengths and fiber length distributions of pulp and paper can be measured using light polarizing optics in the range of 0.1 mm to 7.2 mm.
