The problem of enhancing the contrast of optical images in a strongly scattering medium by means of luminescent and absorbing dyes, topical in laser tomography, is examined. Preparations based on diphthalocyanine compounds were selected on the grounds of their tropism and resistance to the action of heat and light. Images with enhanced contrast in model scattering media (an aqueous solution of milk and margarine) were obtained in the IR region of the spectrum using the radiation of a picosecond neodymium laser.
