Abstract

A holographic interferometer architecture using a photorefractive crystals a the reference image storage device to test the refractive index distribution of the 3D temperature field of a flame is proposed. A novel method in data processing for the purpose of depressing noise and improving the quality of interferogram, spatial filtering, is introduced. Preliminary experimental studies are made to verify the effectiveness of this set-up and the method, the results are in full agreement with our theoretical expectations.
