description ref An optical device for motor vehicles, designed to detect the condition of the road surface, comprises a unit for the emission of electromagnetic radiation in the direction of the road surface to be detected, a receiving unit coupled to an optical element for focusing the radiation back-diffused by the road surface and an electronic control and processing unit for receiving signals at output from said receiving unit and for processing them in order to determine the condition of the road surface, on the basis of a reference map. Appearing in said map are the values of the intensity of radiation Iback-reflected at a reference wavelength and at least one second wavelength. The map is divided into subareas identified beforehand as corresponding to the different conditions of the road surface.
