Claim:
1. A method for measuring the effectiveness of an additive added to an aqueous pulp slurry for decreasing macrostickie contaminants, the method comprising: shining light into an aqueous pulp slurry comprising macrostickie and non-macrostickie contaminants flowing across a streamlined body; adding a hydrophobic dye to the aqueous pulp slurry, such that the hydrophobic dye interacts with the macrostickie and non-macrostickie contaminants, the interaction causing a first modified fluorescent emission; capturing a digital image of the first modified fluorescent emission, the digital image having a background; correcting the background of the digital image; filtering from the digital image the first modified fluorescent emission caused by the non-macrostickie contaminant to create a first filtered image; adding an additive to the aqueous pulp slurry; repeating the shining, adding, detecting, capturing, correcting, and filtering to create a second filtered image; and comparing the first filtered image to the second filtered image to determine the effectiveness of the additive; wherein the streamlined body narrows the flow of the aqueous pulp slurry in the measurement area.
