где v - скорость света в среде объекта;
τ - длительность лазерного импульса, τ ≥ 10 с;
G - максимальный инкремент усиления вынужденного комбинационного рассеивания в канале генерации и формирования стоксовых импульсов.A device for obtaining layer-by-layer optical images of light-scattering objects, containing a pulsed laser, optically communicated with a channel for generating and generating Stokes pulses and a channel for generating and delaying laser pulses, the output of the latter being communicated with a brightness amplifier based on a Raman-active medium, with which the output is also communicated receiving optical system, and the output of the amplifier through spectral filters is communicated with a photo-recording unit, characterized in that the Raman active medium can la generation and formation of the Stokes pulse is formed as a crystal growth rate with the pursuit gain of stimulated Raman scattering is not less than 0.8 GW / cm, and the receiving optical system - with a depth of field
where v is the speed of light in the environment of the object;
τ is the laser pulse duration, τ ≥ 10 s;
G is the maximum gain increment of stimulated Raman scattering in the channel of generation and formation of Stokes pulses.
