Fibre Network Generation andAnalysis : Method for simulation of inhomogeneous static fibre networks

Abstract: In paper optics, advanced modeling of the interaction of light with complex structuresare required for optimization of the optical properties of paper. Monte Carlosimulation routines have been developed in an Open Source project, PaperOpt, inorder to simulate light scattering in paper. The goal of the project is to make the toolmore modular and extensible so that researchers within the paper optics field canmake their own contributions to the model. This thesis is a part of Open PaperOptproject and its goal is to generate paper structures that resemble real paper sheets.This Master’s thesis describes the design and implementation of a model forgeneration of virtual fiber networks with controlled fiber distribution within the papersheet. A C++ written program that generates a fiber network according to a fibermass distribution table has been developed. A qualitative and quantitative comparisonbetween simulated paper structures and real paper obtained from beta-scanmeasurements is also described.
