Query: Roughness spectroscopy of particle monolayer: Implications for spectral
  analysis of the monolayer image   Surface roughness of particle monolayer is one of its fundamental
characteristics, conventionally described in terms of power spectral density.
We derive a general equation for this function and demonstrate its similarity
to those applied in the theory of scattering. We validate our analytical
results by comparison with numerical results for a system with parameters
corresponding to typical experimental conditions. We also demonstrate a
practical application of our approach for spectral analysis of the monolayer
image. Our theoretical model provides a general framework for a cheap and easy
parametrization of particle monolayers.
