Abstract

With respect to the future investigation of asymmetrical types of transparent objects such as plasmas, air and fluid flows, the autor aim was to develop and test an optical set-up which allows a tomographic study of stationary inhomogeneous phase objects on the basics of holographic interferometry along with two mathematics methods of transmission computed tomography (TCT) in order to obtain three dimensional distribution of the index of refraction and temperature. For this two TCT methods -- convolution backprojection method and orthogonal polynomial method -- were used in our experiment with a flame as a testing object. We modified the set-up based on a Mach-Zehnder interferometer, which enables us to use only one holographic plate and low power laser.
