	Phenomenon -
		It is possible to list the phenomena which are relevant to almost any field of endeavor, for example, in the case of optics and light one can list observable phenomena under the topic optical phenomenon.
		A phenomenon (plural: phenomena) is an observable event, particularly something special (literally something that can be seen, derived from the Greek word phainomenon = observable).
		Phenomena make up the raw data of science.

	Minnaert and beyond
		This page is entirely devoted to optical rainbowlike phenomena in and outside earth's atmosphere.
		These phenomena could be a manifestation of some sort of weak 'moonvolcanism' or outgassing, or the mysterious phenomenon, known as Lunar dust migration or Lunar dust levitation : a kind of electrostatic 'duststorm', travelling along with the lunar terminator (sunrise/ sunset on the moon).
		because these effects are nothing else than light coming from a certain direction, in respect to the (optically infinite) pointlike lightsource that produces them.

		Common optical phenomena are often due to the interaction of light from the sun or moon with the atmosphere, clouds, water, or dust and other particulates.
		An optical phenomenon is any observable event which results from the interaction of light and matter.
		Observations of some phenomena such as the photoelectric effect, the flow of electric current in a material or through a vacuum (as in a photocell) when the material is exposed to light, led to advances in science, as they could not be easily explained by existing theory.

	Sky Optics and Observations
		Auroras are quite different from the other optical phenomena visible in the sky in that it is not produced by sunlight necessarily reflecting, refracting or being scattered by any cloud or atmospheric molecule.
		Nearly all optical phenomena seen in or involving the atmosphere entails scattering, reflecting, refracting, or diffracting.
		This phenomenon is called a corona, and it is due to the diffraction of light.

	HALOS
		Halos are optical phenomena that appear in the sky near or around the Sun or Moon, for example "sun-dogs" or the parahelia, or a paraselene or "mock-moon." There are many other types of halos, but they are all caused by ice crystals high in the atmosphere.
		Optical phenomena such as halos were used as an empirical means of weather forecasting before meteorology was developed.
		The particular shape and orientation of the crystals is responsible for the type of halo observed.

	ATMOSPHERIC OPTICAL PHOTOGRAPHY
		For photography of optical phenomena, I recommend you to have a manual camera ready all the time at home, and a small compact camera with you all the time.
		When an optical phenomenon suddenly occurs, you can take action immediately, without first having to change lenses (Prakticas have lenses that must be screwed on and off the camera, really awesome work if you're in a hurry!)
		It is absolutely necessary to study some books about atmospheric halos, sunsets, and other phenomena.

	NASA Tech Briefs: Adaptive multiplexing for free-space optical communication
		* In free-space optical communications, various phenomena can affect the propagation and reception of laser beams; these phenomena include jitter of transmitter and receiver platforms and atmospheric attenuation and distortion of laser beams.
		In a conventional free-space optical communication system, data are transmitted at a constant rate that is not changed to adapt to changing conditions; consequently, for example, a sudden change in weather can disable the free-space optical link, causing loss of data.
		* Free-space optical communications are not entirely secure because laser beams can propagate beyond intended receivers and therefore can be intercepted by unintended parties.

	Astronomy - Wikipedia, the free encyclopedia
		Optical astronomy is the part of astronomy that uses optical components (mirrors, lenses, CCD detectors and photographic films) to observe light from near infrared to near ultraviolet wavelengths.
		Astronomy (Greek: αστρονομία = άστρον + νόμος, astronomia = astron + nomos, literally, "law of the stars") is the science of celestial objects and phenomena that originate outside Earth's atmosphere, such as stars, planets, comets, galaxies, and the cosmic background radiation.
		Optical and radio astronomy can be performed with ground-based observatories, because the atmosphere is transparent at the wavelengths being detected.
