Paper Abstract

In this paper we outline the problems encountered when doing interferometric testing of very hot objects. We show how the TV-holography (ESPI) system can be used to test objects heated to temperatures close to the melting point of the material. In the experiments we have monitored vibrations, and surface behaviour of objects heated to temperatures close to 3000'C. The tertmratxre limits are apart from microstructure changes and excessive turbulence, set by the accessible laser illumination to suppress the background radiation.
