We consider an inverse problem of determining unknown coefficients for a
one-dimensional analogue of radiative transport equation.
We show that some combination of the unknown coefficients can be uniquely determined
by giving pulse-like inputs at the boundary and observing the corresponding outputs.
Our result can be applied for determination of absorption and scattering properties of an
optically turbid medium if the radiative transport equation is appropriate for describing
the propagation of light in the medium.
