A method for the measurement of the thickness of transparent oil film on water based on laser trigonometry is introduced, and the oil film thickness can be obtained using the displacement of imaging spot and the configuration parameter of the imaging system. So calibration is needed to achieve the geometrical parameters of the imaging system. A simple experimental calibration is performed, a series of corresponding thickness and displacement data can be obtained and a calibration curve is fitted, and the system parameters the object distance of the imaging system and the incident angle of the laser beam are acquired. The experiment is conducted with block gauge, diesel oil and lubricant oil. The research results verify the feasibility of the method presented in this paper, which is applicable to dynamic on-line measurement of oil film thickness of oil spill on sea surface.
