Abstract

I et avtrekk (1) hvor lysabsorberende stoffer er til stede, blir det produsert et antall m skjæringspunk- ter mellom en flerhet av n pulslaserstråler (6) og en flerhet av g plan, vinkelrett på nevnte laser- stråler, idet hvert plan passerer gjennom senteret av en mikrofon (7), for å oppnå en flerhet av m foto-akustiske signaler som kan brukes for den øns- kede måling.
