"Oil film — unpolluted sea surface" contrasts in laser pulsed sensing within the middle IR range at 10.6 μm are studied in a wide region of wind velocities over the sea surface, including high velocities of the wind at which a foam on the sea surface is produced. The equation for the above lidar contrast is derived for the monostatic sensing scheme. It is shown that the contrast at a wavelength of 10.6 μm not only exceeds that at 1.06 μm, but also depends differently on the wind velocity.
