Scattering of visible light by micrometer-scale natural wood fibers is usually treated by assuming fibers to be perfect long cylindrical scatterers. In industrial processes, however, fibers experience deformations and are far from ideal cylinders. Variation in fiber morphology affects their scattering properties and it poses a challenge for reliable process measurements. In this paper, we have studied experimentally scattering of both deformed natural and ideal artificial non-absorbing fibers in aqueous suspension and their response to mass concentration of fibers. Experimental results are compared with the predictions of the Mie theory which is combined with cross-sectional diameter probability distribution of fibers. It is shown that the diameter distribution of the fibers together with Mie theory provides results that agree with experiments in case of both natural and ideal fibers.

使用Mie理论和纤维的概率截面直径预测纤维悬浮液的散射特性

微米级天然木纤维对可见光的散射通常通过假设纤维是理想的长圆柱状散射体来进行处理。但是，在工业过程中，纤维会变形，并且远离理想的圆柱体。纤维形态的变化会影响其散射性能，这对可靠的过程测量提出了挑战。在本文中，我们通过实验研究了变形的天然和理想的人造非吸收性纤维在水悬浮液中的散射及其对纤维质量浓度的响应。将实验结果与Mie理论的预测结果进行了比较，并与纤维横截面直径概率分布相结合。
