On a des radars lidar pas optique ....
Donc le brouillard oui mais non.
lidar = "light detection and ranging". L'infra-rouge proche (900 nm), un peu meilleur dans le brouillard, compte aussi comme de l'optique.
Tu dois confondre avec radar
In the case of dense fog with visibility of 200 m, atmo−
spheric extinction coefficient increases dramatically, about
100 times at 0.9 μm band, however in 1.5 μm region it’s
much more – about 500 times. More transparent fog featur−
ing visibility of 0.5 km, produces high optical attenuation as
well – 60 times for 0.9 μm and about 200 times for 1.5 μm. It
can be easily concluded, that fog decreases the range of
rangefinders operating at both wavelengths, however those
based on 1.5 μm optical radiation will suffer much more
comparing to 0.9 μm modules.
