Optics
Optics is the branch of physics which involves the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties.
Optoelectronics
Optoelectronics is the study and application of electronic devices and systems that source, detect and control light, usually considered a sub-field of photonics. In this context, light often includes invisible forms of radiation such as gamma rays, X-rays, ultraviolet and infrared, in addition to visible light. Optoelectronic devices are electrical-to-optical or optical-to-electrical transducers, or instruments that use such devices in their operation. Electro-optics is often erroneously used as a synonym, but is a wider branch of physics that concerns all interactions between light and electric fields, whether or not they form part of an electronic device.
Optics
As men of inward light are wont
To turn their optics in upon't.
Samuel Butler, Hudibras, Part III (1678), Canto I, line 481, reported in Hoyt's New Cyclopedia Of Practical Quotations (1922), p. 593
Optics
Why has not man a microscopic eye?
For this plain reason, Man is not a Fly.
Say, what the use, were finer optics giv'n,
T' inspect a mite, not comprehend the heav'n?
Alexander Pope, An Essay on Man (1733-34), Epistle I, line 193.
Optics
Contemporary with Vitellio and Peccam was... Roger Bacon, a man of almost universal genius, and who wrote on almost every branch of science. He frequently quotes Alhazen on the subject of optics, and seems to have carefully studied his writings, as well as those of other Arabians, which were the fountains of natural knowledge in those days, and which had been introduced into Europe by means of the Moors in Spain. Notwithstanding the pains this great man took with the subject of opticks, it does not appear that, with respect to theory, he made any considerable advance upon what Alhazen had done before him.
Joseph Priestley, The History and Present State of Discoveries Relating to Vision, Light, and Colours (1772)
From air quality to solar radiation, information on our atmosphere is of crucial importance to us all. In order to make the right decisions for our current and future quality of life, European decision makers, businesses and citizens need reliable and up-to-date information on exactly what is going on in our atmosphere now and what to expect in the future.
