Abstract

A basic description of the system for optical tomography with diffusive illumination of the phase object is presented. The configuration of the system allows automatic projection scanning of the studied phase object (such as a burner flame or temperature fields around heated elements) in the range of viewing angles from 0 deg to 90 deg. The object’s projections are obtained using multidirectional holographic interferometry and consequently digitized by a CCD camera. A computer then calculates the wavefront deformation for each projection, and the subsequent tomographic reconstruction of each horizontal slice of the object is processed. Finally, all slices are interpolated and displayed. Here we present the experimental setup along with some experimental results.
