Abstract
1. Дистанционный способ обнаружения нефтяных загрязнений путем облучения поверхности в ультрафиолетовом диапазоне на длине волны возбуждения и регистрации флуоресцентного излучения, отличающийся тем, что для зондирования земной поверхности регистрируют нормированную интенсивность флуоресцентного излучения I(λ), I(λ), I(λ) в трех узких спектральных диапазонах с центрами на длинах волн λ, λ, λ, выбранных по данным экспериментальных измерений из условия максимальной вероятности правильного обнаружения нефтяных загрязнений, а о наличии нефтяных загрязнений судят по выполнению пороговых соотношений:2. Дистанционный способ обнаружения нефтяных загрязнений по п.1, отличающийся тем, что длина волны возбуждения принимается равной 266 нм, при этом λ=331,5 нм, λ=351,5 нм и λ=417,5 нм, а пороговые значения K1; K2; K3 при нормировке интенсивности флуоресценции на интенсивность сигнала рассеяния на длине волны возбуждения 266 нм приняты равными: K1=3·10; K2=1,8; K3=1,75.1. A remote method for the detection of oil pollution by irradiating the surface in the ultraviolet range at a wavelength of excitation and recording fluorescence radiation, characterized in that the normalized fluorescence radiation intensity I (λ), I (λ), I (λ) three narrow spectral ranges with centers at wavelengths λ, λ, λ, selected according to experimental measurements from the condition of maximum probability of the correct detection of oil pollution, and the presence of yanyh contamination judged to fulfill the relations of the threshold 2. The remote method for detecting oil pollution according to claim 1, characterized in that the excitation wavelength is taken to be 266 nm, with λ = 331.5 nm, λ = 351.5 nm and λ = 417.5 nm, and threshold values K1; K2; K3 when normalizing the fluorescence intensity to the intensity of the scattering signal at an excitation wavelength of 266 nm is taken equal to: K1 = 3 · 10; K2 = 1.8; K3 = 1.75.
