In a recent publication [1] we developed a model that reproduces the propagation of photons through an aerosol cloud and used it to separate individual scattering order contribution. This model is based on the known principle that the modulation transfer function (MTF) of cascaded lenses is equivalent to the product of the lenses’ MTFs. After the publication, we found that a model for underwater propagation based on the same principle was published by Willard H. Wells in 1969 [2]. A reference to Wells’ paper should have appeared in our publication.
