Monte Carlo simulation of the light scattering from a network of paper fibres
Acreo¿s Grace model is a Monte-Carlo simulation program for calculating light scattering from printed paper. It describes paper as a three-dimensional structure including rough surfaces and a statistical description of the paper components such as fibres or fillers. The paper is divided in several layers such as coatings, basesheets, and print layers.
Most of the Monte-Carlo simulation part has been recently rewritten in C++ with significant speed increase as a result. The goal of this Master¿s thesis is to implement and improve a C++ version of the scattering in a network of fibres for which a first model is implemented in Matlab. The first task is thus to translate the code and adapt the code structure to the main program. Several enhancements will then be implemented and tested. The second task is to develop routines dedicated to the optimisation of the input parameters to experimental measurements.
The goal of the master¿s thesis is to implement and further develop our Monte-Carlo model for light scattering by a network of paper fibres. The work involves implementing a model previously written in Matlab into C++ and then developing some optimisation routines to fit the model parameters to experi-mental measurements.
