In the dissertation a new method for the analysis of measurement results was invented and implemented. This method is applicable to consistency measurements in the paper and pulp industry and also to the measurements required in nanocellulose manufacturing processes. The measurement method itself is a previously known combination of tube flow fractionation and optical measurement, where the tube flow fractionation separates the pulp sample into different parts which can then be measured as individual fractions. This qualitative separation improves the performance of the optical measurement.

Dissertation

Analytical methodologies to analyze optical and polarization properties over time and the obtained results were utilized in biomedical and food science applications. In this thesis, soft biological tissues (pork samples) were selected as a biological tissue due to their similarity to human tissue. First, the relative spectral changes of absorbance were studied by applying two different custom-built configurations. Second, a novel application of Mueller matrix (MM) imaging polarimetry was pioneered to visualize the dynamics of the tissue polarization properties over time with a custom-built Mueller matrix imaging polarimeter (MMIP). Finally, a new Stokes-polarimetry was introduced to examine optically thin histological sections from optically anisotropic biological tissues with different morphological structures.

The ultimate goal is to find the way to determine the most subtle changes in cells’ or organelles utilizing a new paradigm in modern optics and photonics, known as a twisted light, i.e. the light carrying orbital angular momentum. The alterations of properties of twisted light, serving as the markers of certain diseases, provide a unique opportunity to detect cancer and other tissue malformations with the sensitivity beyond the conventional biopsy modalities.
