These authors proved, however, that no optical system can justify these suppositions, since they are contradictory to the fundamental laws of reflexion and refraction.

These different factors affect the diamond's hardness, smoothness, conductivity, optical properties and more.

These lenses are analogous to but different from the glass lenses of an optical microscope that form a magnified image by focusing light on or through the specimen.

These characteristics make Hall effect devices better for position sensing than alternative means such as optical and electromechanical sensing.

These microscopes have the same resolution limit as wide field optical and electron microscopes.

These three-wave mixing processes correspond to the nonlinear effects known as second harmonic generation, sum frequency generation, difference frequency generation and optical rectification respectively.

These laws were discovered empirically as far back as 984 AD and have been used in the design of optical components and instruments from then until the present day.

These pearls, which are often pink in color, are a by-product of the conch fishing industry, and the best of them display a shimmering optical effect related to chatoyance known as ' flame structure '.

These photons are fed back into the laser medium, usually by an optical resonator.

These issues are more difficult for optical approaches as the timescales are orders of magnitude shorter and an often-cited approach to overcoming them is optical pulse shaping.

These include photon scanning microscopy ( PSTM ), which uses an optical tip to tunnel photons ; scanning tunneling potentiometry ( STP ), which measures electric potential across a surface ; spin polarized scanning tunneling microscopy ( SPSTM ), which uses a ferromagnetic tip to tunnel spin-polarized electrons into a magnetic sample, and atomic force microscopy ( AFM ), in which the force caused by interaction between the tip and sample is measured.

These include meso compounds, cis-trans ( E-Z ) isomers, and non-enantiomeric optical isomers.

These cables are known as optical ground wire ( OPGW ).

These pattern sequences are used to measure jitter and eye mask of TX-Data in electrical and optical data links.

These connections are made either with twisted pair wire, normally referred to as jumper wire, or with optical fiber cables, normally referred to as jumper cables.

These will contain within them an optical switch, which will, in some cases, be a photonic switch.

These spatially varying optical parameters do not correspond to any natural material, but may be implemented using metamaterials.

These structures may be the edge of a lens or mirror, or a ring or other fixture that holds an optical element in place, or may be a special element such as a diaphragm placed in the optical path to limit the light admitted by the system.

) These optical pairs are resolvable by the naked eye.

These hybridized glasses have a very low level of optical dispersion ; only two compiled lenses made of these substances can yield a high level of correction.

These kinds of crystals have one or two optical axes.

These losses depend on fiber diameter and length, absorption coefficient, the mean value of the loss per internal reflection and last, but not least, on the angular distribution of the incident light.

These two theories respectively evolved the doctrine of individual and universal immortality, or the absorption of the individual into the eternal One.

These pigments are named after the wavelength ( in nanometers ) of their red-peak absorption maximum.

( These rules do not necessarily apply to Two-photon absorption.

These would be stored in tanks that would prevent a critical mass from forming by some combination of geometry or neutron absorption ( for example: long tubes made out of boron in an array with considerable spacing between tubes ).

These cytokine factors are released into general circulation, where they migrate to the circumventricular organs of the brain due to easier absorption caused by the blood – brain barrier's reduced filtration action there.

These volatile chemicals yield important performance characteristics, primarily density reduction, cushioning / energy absorption and thermal insulation.

These processes are observed in the neighborhood of their characteristic absorption frequencies.

These bacteria also produce large amounts of vitamins, especially vitamin K and biotin ( a B vitamin ), for absorption into the blood.

These dark fixed lines were later shown to be atomic absorption lines, as explained by Kirchhoff and Bunsen in 1859.

These lipoproteins are both necessary for the absorption of fats, cholesterol, and fat-soluble vitamins from the diet and necessary for the efficient transport of these substances in the bloodstream.

These include spectral interferences caused by absorption band overlap, fading of the color of the absorbing species ( caused by decomposition or reaction ) and possible composition mismatch between the sample and the calibration solution.

These creatures do not have this need, as the surface area to volume ratio is large enough to allow absorption of nutrients and gas exchange by diffusion alone, due to dorso-ventral flattening.

These absorption bands lie partly in the so-called vacuum ultraviolet ( wavelengths less than about 200 nm ).

These technologies use different mechanisms to facilitate the absorption and action of a chemotherapy drug instilled directly into the bladder.

These dietary characteristics may lower risk of diabetes, obesity and other related syndrome X diseases by placing less stress on the pancreas to produce insulin due to staggered absorption of glucose, thus preventing insulin insensitivity.

These changes can also be combined ( e. g. rotation-vibration transitions ), leading to new absorption lines at the combined energy of the two changes.

These absorptions can mask or confound the absorption spectrum of the sample.

These are the sites of light absorption and ATP synthesis, and contain many proteins, including those involved in the electron transport chain.

These oscillations are detectable on almost any time series of solar images, but are best observed by measuring the Doppler shift of photospheric absorption lines.

These resonant and non-resonant cavity enhanced absorption technqies have so far not been used that frequently with TDLAS.

These changes may occur in oral protective reflexes ( dryness of the mouth caused by diminished salivary glands ), in the gastrointestinal system ( such as with delayed emptying of solids and liquids possibly restricting speed of absorption ), and in the distribution of drugs with changes in body fat and muscle and drug elimination.

These compounds produce broad-band absorption when they react to form dyes, allowing for more natural-looking hair colors.

The quantum dot absorption features correspond to transitions between discrete, three-dimensional particle in a box states of the electron and the hole, both confined to the same nanometer-size box. These discrete transitions are reminiscent of atomic spectra and have resulted in quantum dots also being called artificial atoms.

These absorption lines result from intergalactic gas through which the galaxy or quasar's light has traveled.
