WebRayleigh scattering of sunlight in Earth's atmosphere causes diffuse sky radiation, which is the reason for the blue color of the daytime and twilight sky, as well as the yellowish to reddish hue of the low Sun. Sunlight is also subject to Raman scattering, which changes the rotational state of the molecules and gives rise to polarization effects. WebIn order to isolate the target signal from sunlight and other extraneous light sources, LIDAR interference filters must be specified with wide range out-of-band blocking. Blockers are designed using dielectric reflectors where the mirror pairs are stacked and ultimately manipulated so that the filter attenuates light across broad wavelength ...
