Development of optical introscopy in medical engineering

Transmission optical tomography is a promising method for medical diagnosis. However, in spite of significant effort, no commercial TOT tomograph model is presently available, and so this method has not yet been introduced into medical practice. This is primarily due to the difficulty of mathematical description of the interaction of laser radiation with highly dispersive biological medium (HDM). The goal of this work was to describe the results of measurement of time distribution of laser pulse propagating through a homogeneous layer of model HDM (milk dissolved in water) and determination of the optical characteristics of the medium at various concentrations of the disperser (milk).
