Abstract

The theory and experimental method of measuring flame temperature field with two-reference phase-shifting holographic interferometry and CT technique are studied in this paper. By recording the relative intensity distributions of three-step phase-shifting each view direction, we obtained the accurate phase distributions used to reconstruct the refractive index field. The cross section temperature field of a double-candle flame is measured, and the sources of experimental and other error are also discussed.
