A simulated sea surface with a Pierson-Neumann power spectrum was generated by a numerical model. The image was recorded on photographic film by means of a microdensitometer with a writing mode. To obtain the bidimensional power spectrum of this simulated image of the sea surface, a coherent optical system was used. This power spectrum has information about frequencies in the highest energy peak and the direction that the waves have at a specific time. The Pierson-Neumann power spectrum used to generate the simulated sea surface was compared with the bidimensional power spectrum obtained with the coherent optical system. Attenuation of the high frequencies in the measured spectrum was observed. This attenuation was probably caused by distribution of density values in the film or by the aperture of the detector used in the coherent optical system. Optical autocorrelations of the simulated sea surface were obtained, and a high degree of correlation in the direction perpendicular to the wind was found.
