TWO-ANGULAR REMOTE METHOD OF DETECTION OF OIL POLLUTION ON WATER SURFACE Russian patent published in 2009 - IPC G01N21/55 

FIELD: physics; measuring.

SUBSTANCE: invention concerns to the measuring technics and can be used for operative detection of floods of oil and mineral oil in the seas and interior reservoirs. The method consists in irradiation of a surface and obtaining of the reflected signal which carry out for two corners. As parametres of the reflected radiation choose powers of the signals gained at the irradiation of a surface vertically downwards and under a corner to a vertical and presence of an oil film judge on performance simultaneously two relations: P_oM>P_owM_w and M<M_w, where: P_o, P_ow - powers of signals from an explored and pure water table for a bundle guided vertically downwards, P_x, P_xw and P_y, P_yw - powers of signals from an explored and pure water table for a bundle guided under a corner θ to vertical, for lines of flight along an axis x and axis y, accordingly.

EFFECT: simplification of hardware embodying at high reliability of detection.
