Forward scattering induced by water drops on a transmissive substrate.
In this study the scattering of radiation by condensation drops deposited on a single glass plate is dealt with. Experiments were carried out in the visible radiation range by means of a laboratory measuring unit as a function of three parameters, namely, the phase of the condensation process, the wavelength of the incident radiation, and the radiation incidence angle. The experiments indicated that during the condensation process a steady state in the scattering pattern of single glass occurred after a transition phase. Owing to the condensate, more than 80% of the transmitted visible radiation was scattered. The scattering slightly diminished with increasing wavelength, from 400 to 700 nm, and the asymmetry of the scattering pattern enlarged with increasing incidence angle of the radiation.
