To deduce the optical properties, the absorption coefficient
and reduced scattering coefficient 
, of turbid medium, Lin et al. ( Appl. Opt. 34 : 2362-1995 ) proposed an
oblique incidence reflectometry in which
the diffusion approximation was assumed.
In this paper we propose an alternative method
which does not assume the diffusion approximation
but uses a Monte Carlo light propagation
model. Two features are extracted from the
diffuse reflectance distribution detected
on the medium surface, and optical properties
are then estimated by looking up the predetermined
table generated by Monte Carlo simulations. The validity of the proposed
method has been confirmed by computer simulations
