Paper Abstract

This paper deals with error analysis of experimental data of a laser speckle photography (LSP) application which measures a temperature field of natural convection around a heated cylindrical tube. A method for error corrections is proposed and presented in detail. Experimental and theoretical investigations have shown errors in the measurements are induced due to four causes. These error sources are discussed and suggestions to avoid the errors are given. Due to the error analysis and the introduced methods for their correction the temperature distribution, respectively the temperature gradient in a thermal boundary layer can be obtained more accurately.
