  2. Atmospheric optics - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_optics

    Cloud droplets tend to scatter light efficiently, so that the intensity of the solar radiation decreases with depth into the gases. As a result, the cloud base can vary from a very light to very dark grey depending on the cloud's thickness and how much light is being reflected or transmitted back to the observer.

    Another defense is photochromic materials able to become opaque under high light energy densities. Nonlinear optics techniques are being investigated: e.g. vanadium-doped zinc telluride (V:ZnTe) can be used to form electro-optic power limiters able to selectively block the intense dazzler beam without affecting weaker light from an observed scene.

    The first scientific description of the crown flash phenomenon appears to be in the journal Monthly Weather Review in 1885, [4] according to the Guinness Book of Records. [5] Also mentioned in Nature in 1971 [ 6 ] and in a letter to Nature slightly earlier in the same year, [ 7 ] this phenomenon is regarded as uncommon and not well documented.

    The Journal of Electronic Defense reported that "plasma-cloud-generation technology for stealth applications" developed in Russia reduces an aircraft's RCS by a factor of 100 (20 dB). According to this June 2002 article, the Russian plasma stealth device has been tested aboard a Sukhoi Su-27 IB fighter-bomber.
