Query: Reflection statistics of weakly disordered optical medium when its mean
  refractive index is different from an outside medium   Based on the difference between mean background of an optical sample
refractive index n_0 and an outside medium, n_out, different than n_0, we study
the reflection statistics of a one-dimensional weakly disordered optical medium
with refractive index n(x)=n_0+dn(x). Considering dn(x) as color noise with the
exponential spatial correlation decay length l_c and k as the incident wave
vector, our results show that for the small correlation length limit, i.e.
k*l_c<1, the average value of reflectance, r, follows a form that is similar to
that of the matched refractive-index case n_0=n_out, i.e., <r(dn, lc)>
proportional to <dn^2>l_c. However, the standard deviation of r is proven to be
std(r(dn,l_c)) proportional to sqrt(<dn^2>l_c), which is different from the
matched case. Applications to light scattering from layered media and
biological cells are discussed
