Abstract

Kuituhiukkasten hienoainekseksi hajoamisen asteen määrittäminen paperimassassa suoritetaan johtamalla (1000) optista säteilyä paperimassaan (104); ja määrittämällä (1002) kuituhiukkasten hienoainekseksi hajoamisen aste paperimassassa (104) paperimassan (104) kanssa vuorovaikutuksessa olevien ainakin kahden eri optisen kaistan (106) optisten tehojen ensisijaisen havainnoinnin perusteella, ja ainakin yhden seuraavista toissijaisista havainnoista perusteella: paperimassan (104) läpi edenneen optisen säteilyn polarointi, paperimassan (104) läpi edenneen mikroaaltosäteilyn ominaisuus, paperimassan (104) ja materiaalin rakenteen (400, 504, 506) välisen liikkeen aiheuttama voima paperimassassa (104), ja hiukkaset ainakin yhdessä paperimassan (104) kuvassa.
