Abstract

The novel laboratory system for the optical tomography is used to obtain three-dimensional temperature field around a heated element. The Mach-Zehnder holographic interferometers with diffusive illumination of the phase object provide the possibility to scan of multidirectional holographic interferograms in the range of viewing angles from 0 deg to 108 deg. These interferograms form the input data for the computer tomography of the 3D distribution of the refractive index variation, which characterizes the physical state of the studied medium. The configuration of the system allows automatic projection scanning of the studied phase object. The computer calculates the wavefront deformation for each projection, making use of different methods of Fourier-transform and phase-sampling evaluations. The experimental set-up together with experimental results is presented.
