91Electro-optic modulator — (EOM) is an optical device in which a signal controlled element displaying electro optic effect is used to modulate a beam of light. The modulation may be imposed on the phase, frequency, amplitude, or direction of the modulated beam. Modulation… …
92Sonoluminescence — is the emission of short bursts of light from imploding bubbles in a liquid when excited by sound.HistoryThe effect was first discovered at the University of Cologne in 1934 as a result of work on sonar. H. Frenzel and H. Schultes put an… …
93Ozone depletion — Image of the largest Antarctic ozone hole ever recorded (September 2006) Ozone depletion describes two distinct but related phenomena observed since the late 1970s: a steady decline of about 4% per decade in the total volume of ozone in Earth s… …

95Fourier transform — Fourier transforms Continuous Fourier transform Fourier series Discrete Fourier transform Discrete time Fourier transform Related transforms The Fourier transform is a mathematical operation that decomposes a function into its constituent… …
96Ionization — is the physical process of converting an atom or molecule into an ion by adding or removing charged particles such as electrons or other ions.This process works slightly differently depending on whether an ion with a positive or a negative… …
97Triboluminescence — is an optical phenomenon in which light is generated via the breaking of asymmetrical bonds in a crystal when that material is scratched, crushed, or rubbed. This is a variant of luminescence; the term comes from the Greek tribein (to rub) and… …
98Cathodoluminescence — is an optical and electrical phenomenon whereby a beam of electrons is generated by an electron gun (e.g. cathode ray tube) and then impacts on a luminescent material such as a phosphor, causing the material to emit visible light. The most common …
99Electrostatic discharge — (ESD) is the sudden and momentary electric current that flows between two objects at different electrical potentials. The term is usually used in the electronics and other industries to describe momentary unwanted currents that may cause damage… …
100LIGO — For the Latvian holiday Ligo, see Jāņi.LIGO stands for Laser Interferometer Gravitational Wave Observatory. Cofounded in 1992 by Kip Thorne and Ronald Drever of Caltech and Rainer Weiss of MIT, LIGO is a joint project between scientists at MIT… …
