Abstract

Capabilities of laser speckle photography, speckle shearing interferometry, and Talbot interferometry with circular gratings to measure the temperature profile of axisymmetric gaseous flames are studied. Detailed experimental and theoretical investigations are presented. The temperatures measured by these three techniques are compared with the temperatures measured by a platinum-platinum-rhodium thermocouple with an accuracy of measurement ±0.2% of full scale ±4 digits. Good agreement between them is seen.
