Abstract

Et system (20) omfattende en lyskildeinstrumentering (30) for selektivt å belyse et lysspredningsmedium som omfatter en luminofor, og en deteksjonsinstrumentering (50) for å detektere mangedobbelt spredt lysutmating fra mediet som reaksjon på belysning ved hjelp av lyskildeinstrumenteringen (30). En prosessor (70) er operativt koplet til deteksjonsinstrumenteringen (50) for å bestemme en første optisk karakterisering av mediet ut fra en første mangedobbelt spredt lysutmating med en første belysningslysbølgelengde, og en andre optisk karakterisering av mediet ut fra en andre mangedobbelt spredt lysutmating med en andre belysningslysbølgelengde som er forskjellig fra den første belysningslysbølgelengde. Prosessoren (70) er operativ for å beregne levetid av luminoforen ut fra den første optiske karakterisering, den andre optiske karakterisering, og en mangedobbelt spredt emisjon av luminoforen fra mediet som reaksjon på eksitasjon.
