SAMMENDRAG
En fremgangsmåde til undersøgelse af materialer i fast aggregatform, f.eks. metaller, med hensyn til deres overfladefejl, overfladerevner eller lignende, egenskaberne af belægninger eller overfladekvaliteten af papir. En særlig anvendelse af fremgangsmåden ifølge opfindelsen er måling af tykkelsen af det hærdede overfladelag af stål.
Af hensyn til at forhindre hurtig udligning af temperaturforskelle, der frembringes på materialets overflade er der på materialet (25) rettet en pulserende lysstråle (21) i bølgelængdeområdet for synligt lys, hvorved i det mindste en del af denne lysstråle (21) absorberes i overfladen af materialet (25) og forårsager forøgelse af materialets overfladetemperatur. Overfladen af materialet (25) , der er blevet opvarmet ved virkning af den frembragte, periodiske temperaturvariation udsender en pulserende, infra-rød stråling (26), som modtages med midler (27), der er følsomme for infra-rød stråling.
