Abstract

There are some difficulties in the use of a well-known X-ray computer tomography technique due to the strong light scattering in biological tissues. We propose to analyze the whole light scattering picture for the development of novel processing algorithms in tomographical imaging. Time-resolved experiments on the forward scattering of IR-light from a model of biological media illuminated by a picosecond YAG-laser with 10 ps pulse duration have been performed. The scattering radiation was recorded by a streak camera having 1.5 ps time resolution. From these results and theoretical considerations the analytic expression for intensity against time distribution of the laser radiation passed through the media has been obtained. The expression can be used as the basis for tomographical reconstruction.
