The OSIRIS scientific Key Project is OTELO.

The scientific field that OTELO will allow tackling is very wide, and encompasses evolutionary studies of Ly alpha emitters, QSO, AGN, star-forming populations ( specifically the faint end luminosity ), Emissión line ellipticals ( detectable depending upon its evolution ), chemical evolution of the Universe between z = 0. 24 and z = 1. 5, mass / luminosity relation vs. morphological type and redshift ( up to z = 1. 5 ), Tully-Fisher relation up to z = 1. 5 and derivation of cosmological parameters.

OTELO will complement spectroscopic surveys since the selection criteria are completely different: not broad band based but emission line based, which will allow detecting faint continuum objects.

OTELO will observe objects with an age equivalent to 10 % of the age of the Universe.

Given the observing procedure, OTELO will allow studying a clearly defined volume of the Universe at a known flux limit.

; OSIRIS: The OH-Suppressing Infrared Imaging Spectrograph is a near-infrared spectrograph for use with the Keck II adaptive optics system.

The IAC's OSIRIS ( Optical System for Imaging and low Resolution Integrated Spectroscopy ), is an " imaging and low resolution spectrograph with longslit and multiobject spectroscopic modes.

It is derived in part by the Mars Express High Resolution Stereo Camera ( HRSC ) and the Rosetta Optical, Spectroscopic and Infrared Remote Imaging System ( OSIRIS ).

OSIRIS ( Optical System for Imaging and low Resolution Integrated Spectroscopy ) is the Spanish Day One instrument for the Gran Telescopio Canarias ( GTC ).

Sensitive in the wavelength range from 365 through 1000 nm, OSIRIS is a multiple purpose instrument for imaging and low-resolution long slit and multiple object spectroscopy ( MOS ).

OSIRIS field of view is of 8. 5 × 8. 5 arcminutes and the maximum nominal spectral resolution is of 5000 for a slit width of 0. 6 arcsec.

OSIRIS takes spectra in a small field of view to provide a series of images at different wavelengths.

In January, 2012 OSIRIS was moved to the Keck I telescope.

Its Day One instrumentation was OSIRIS.

Also of historical note was that the operating system ( OSIRIS ), applications, development tools, and every other piece of BiiN software was written exclusively in Ada — perhaps the largest non-military use of that programming language.

* May 28 — ESA released the first pictures taken with the OSIRIS camera during the April 30 observation tests pointed at comet LINEAR.

* March 12 — The OSIRIS instrument was trained on the future flyby target asteroid Steins for science observation, and the data was downlinked to Earth over three days just before solar conjunction.

OSIRIS observing modes include also fast photometry and spectroscopy.

For example, the James Webb Space Telescope is, as its name indicates, a telescope, but it includes a suite of four distinct scientific instruments: Mid Infrared Instrument ( MIRI ); Near Infrared Camera ( NIRCam ); Near Infrared Spectrograph ( NIRSpec ); Fine Guidance Sensor Tunable Filter Imager ( FGS-TFI ).

Tunable diode laser absorption spectroscopy ( TDLAS ) is a technique for measuring the concentration of certain species such as methane, water vapor and many more, in a gaseous mixture using tunable diode lasers and laser absorption spectrometry.

Outside the field of analytical chemistry, e. g. when used with the Tunable Diode Laser Absorption Spectroscopy ( TDLAS ) technique, the absorbance is often defined using the natural logarithm instead of the common logarithm, i. e. as

* Digitally Tunable Capacitor, a type of capacitor that is used in high performance RF tuning of mobile networks such as GSM cellular and Mobile TV

A review of FELs for medical uses is given in the 1st edition of Tunable Laser Applications.

* Tunable VCSEL: One of the two mirror stacks is movable.

Tunable lasers used in AVLIS include the dye laser and more recently diode lasers.

Tunable lasers are used in swept-frequency metrology to enable measurement of absolute distances with very high accuracy.

Tunable lasers find applications in spectroscopy, photochemistry, atomic vapor laser isotope separation, and optical communications.

( Tunable lasers are those where the wavelength can be altered within a specific range.

Tunable sound-absorbing curtains behind the bronze grilling and banners in the ceiling can be deployed out of sight to dampen or enliven the sound.

Line of pit craters suggests drainage into subsurface voids, possibly created by tension cracks ( Thermal Emission Imaging System | THEMIS IR daytime mosaic ).

* Emission ( electromagnetic radiation ), the process by which the energy of a photon is released by another entity

* Emission theory ( vision ), the proposal that visual perception is accomplished by rays of light emitted by the eyes

To separate and analyze them, the fluorescent radiation is passed through an Emission monochromator, and observed selectively by a detector.

ICAO is currently opposed to the inclusion of aviation in the European Union Emission Trading Scheme ( EU ETS ).

Historically, the word " maser " is derived from the original upper-case acronym MASER, which stands for " Microwave Amplification by Stimulated Emission of Radiation ".

Emission nebulae emit spectral line radiation from ionized gas ( mostly ionized hydrogen ); they are often called HII regions ( the term " HII " is used in professional astronomy to refer to ionized hydrogen ).

The European Pollutant Emission Register is a type of PRTR providing access to information on the annual emissions of industrial facilities in the Member States of the European Union, as well as Norway.

In the 1990s, researchers began to use Electroencephalography ( EEG ), Positron Emission Tomography ( PET ) and more recently functional Magnetic Resonance Imaging ( fMRI ), which is now the most widely used imaging technique to help localize personality traits in the brain.

* Emission indicates that radiative energy is released by the material.

For greenhouse gases the largest is the European Union Emission Trading Scheme, whose purpose is to avoid dangerous climate change.

* Emission is the unwanted generation of electromagnetic energy by some emitter or source.

The principal source of noise in DFAs is Amplified Spontaneous Emission ( ASE ), which has a spectrum approximately the same as the gain spectrum of the amplifier.

The initial spontaneous emission is therefore amplified in the same manner as the signals, hence the term Amplified Spontaneous Emission.

A much higher quality DEM from the Advanced Spaceborne Thermal Emission and Reflection Radiometer ( ASTER ) instrument of the Terra satellite is also freely available for 99 % of the globe, and represents elevation at a 30 meter resolution.

Field Emission Electric Propulsion ( FEEP ) is an electrostatic propulsion concept based on field ionization of a liquid metal and subsequent acceleration of the ions by a strong electric field.

Emission of isoprene is also observed in some bacteria and this is thought to come from non-enzymatic degradations from DMADP.

Emission is the opposite of absorption, it is when an object emits radiation.

Emission from the Sun at centimetric ( radio ) wavelength is due primarily to coronal plasma trapped in the magnetic fields overlying active regions.

One trademark product of urea solution, also referred to as Diesel Emission Fluid ( DEF ), is AdBlue.

Emission of radiation is typically described using semi-classical quantum mechanics: the particle's energy levels and spacings are determined from quantum mechanics, and light is treated as an oscillating electric field that can drive a transition if it is in resonance with the system's natural frequency.
