Abstract

Podstata vynálezu spočívá v tom, že se ohřívaná oblast materiálu ohřeje bezkontaktně působícím ohřívajícím tepelným tokem a po ukončení ohřevu se ve fázi chladnutí v předem stanoveném čase homogenizace teploty povrchu v oblasti vyhodnocení emisivity v průběhu nestacionárního procesu změří plošné rozložení vyzařovaného tepelného toku z povrchu materiálu v měřené oblasti, a v jednotlivých místech oblasti vyhodnocení emisivity se stanoví emisivita výpočtem.
