The urgent problem of monitoring oil pollution on water surface is considered. Laser
spectrophotometric method for measuring thickness of petrochemical film on river, lake
and sea water areas is developed. Laser meter uses four wavelengths of radiation.
It is
located at an aircraft carrier, and irradiates the sea surface vertically downwards. It is
shown that developed laser four-wave method allows measuring thickness of thin oil
films and petrochemical films (thickness less than wavelength of laser radiation) on
rough sea surface with an error of 20 percent or less.
Keywords:
laser method, sea surface, petrochemical film, film thickness measurement.
