Abstract

The aim of this paper is to present a method of optical imaging of the objects inside high scattering media. An idea of two-wavelength tomography is based on application of differences in absorption spectra of transmitted light for two selected wavelengths i.e. 670 nm and 810 nm. In the first part of the paper a theoretical background of optical tomography is done. Radon transform procedures for monochromatic light as well as for two-wavelength case are given. In the second part of the paper results of experiments carried out in laboratory by use of two laser diodes as a light source and CCD camera controlled by computer as a detector are presented.
