TOMOGRAPHIC DECONVOLUTION OF LASER SPECKLE PHOTOGRAPHY FOR AXISYMMETRIC FLAME TEMPERATURE MEASUREMENT
SINOPSIS
A laser speckle photography technique can nonintrusively measure thermal flow properties such as medium density, index of refraction or temperature. The laser specklegram records a line-of-sight or path-integrated information on these properties. For varying properties in a medium along the optical path, a mathematical technique called a tomography deconvolves cross-sectional information out of the projected measurement. The present work will outline the underlying principles of optical tomography and show how to apply it to the diagnostic technique of laser speckle photography. Comparisons of temperature measurements using a thermocouple probe against the temperature conversion from the specklegram data have been made for laminar flames. The speckle photography technique shows good potential as a new nonintrusive temperature measurement tool for various thermal flows.
