The aberrations of the third order are: (1) aberration of the axis point; (2) aberration of points whose distance from the Aberra- axis is very small, less than of the third order - the tions of deviation from the sine condition and coma here fall together in one class; (3) astigmatism; (4) curvature of the field; (5) distortion. The implication was clear: to discuss Article 6 would be an irresponsible aberration. "they described the outbreak of violence in the area as an aberration" synonyms:- anomaly, … The indirect method is based upon the observed constant of aberration or the displacement of the stars due to the earth's motion. Thus in estimating the intensity at a focal point, where, in the absence of aberration, all the secondary waves would have exactly the same phase, we see that an aberration nowhere exceeding 4X can have but little effect. Assured that his explanation was true, Bradley corrected his observations for aberration, but he found that there still remained a residuum which was evidently not a parallax, for it did not exhibit an annual cycle. They evolve every time they get electrocuted, drowned, or burnt. During the 19th century, the hesitation about Colossians led to the rejection of Philemon by some critics as a pseudonymous little pamphlet on the slave question - an aberration of literary criticism (reproduced in Ency. a state or condition markedly different from the norm 2. a disorder in one's mental state 3. an optical phenomenon resulting from the failure of a lens or mirror to produce a good image.

The removal of the spherical aberration and the sine-condition can be accomplished only for two conjugate points. A further aberration which can only be overcome with difficulty, and even then only partially, is the " curvature of the field, " i.e. Again, since the constant of aberration defines the ratio between the velocity of light and the earth's orbital speed, the span of the terrestrial circuit, in other words, the distance of the sun, is immediately deducible from known values of the first two quantities. A simple rule will find the position of the star due to aberration. By using these glasses and employing minerals with special optical properties, it is possible to correct objectives so that three colours can be combined, leaving only a quite slight tertiary spectrum, and removing the spherical aberration for two colours. A lens system comprising two elements, used to reduce chromatic aberration. When the earth is at A, in consequence of aberration, the star is displaced to a point a, its displacement sa being parallel to the earth's motion at A; when the earth is at B, the star appears at b; and so on throughout an orbital revolution of the earth. 283. The annual aberration is the aberration correction for an imaginary observer at the Earth's center. That last kiss had been a mistake, an aberration. The extension of the image away from the axis or size of field available for covering a photographic plate with fair definition is a function in the first place of the ratio between focal length and aperture, the longer focus having the greater relative or angular covering power, and in the second a function of the curvatures of the lenses, in the sense that the objective must be free from coma at the foci of oblique pencils or must fulfil the sine condition (see Aberration). The component S 1 of the system, situated between the aperture stop and the object 0, projects an image of the diaphragm, termed by Abbe the " entrance pupil "; the " exit pupil " is the image formed by the component S2 j which is placed behind the aperture stop. Since the maximum aperture of the pencils issuing from 0 is the angle u subtended by the entrance pupil at this point, the magnitude of the aberration will be determined by the position and diameter of the entrance pupil. The reduction of almost all visible chromatic aberration at 60x magnification on the base model ES 80 GA SD is a real breakthrough. Source.

Even if the object-point on the axis cannot be reproduced quite free from aberration through such a lens, because aberrations of the type of an under-correction have been produced by the first plane outer limiting surface, yet the defects with the strong refraction are relatively small and can be well compensated by other systems. The chromatic aberration of the object-glass of one of these telescopes is corrected for photographic rays, and the image formed by it is received on a highly sensitive photographic plate. If the pencil with the angle u 2 be that of the maximum aberration of all the pencils transmitted, then in a plane perpendicular to the axis at O' 1 there is a circular " disk of confusion" of radius 0' 1 R, and in a parallel plane at 0'2 another one of radius 0' 2 R 2; between these two is situated the " disk of least confusion.". When all is taken into consideration it is scarcely possible to reduce the secondary colour aberration at the focus of such a double object-glass to less than a fourth part of that prevailing at the focus of a double objective of the same aperture and focus, but made of the ordinary crown and flint glasses.

A second method of correcting the spherical aberration depends FIG. deviating from what is normal or desirable, not typical. peculiarities of the skeleton or portions of the skeleton of certain birds - one of the most remarkable of which is that on the component parts of the foot (pp. (4) After eliminating the aberration on the axis, coma and astigmatism, the relation for the flatness of the field in the third order is expressed by the " Petzval equation," I 1 = o, where is the radius of a refracting surface, n and n' the refractive indices of the neighbouring media, and / the sign of summation for all refracting surfaces. For infinitely distant objects the radius of the chromatic disk of confusion is proportional to the linear aperture, and independent of the focal length (vide supra," Monochromatic Aberration of the Axis Point "); and since this disk becomes the less harmful with an increasing image of a given object, or with increasing focal length, it follows that the deterioration of the image is proportional to the ratio of the aperture to the focal length, i.e. The constant of aberration introduces the sun's distance by a comparison between the velocity of the earth in its orbit and the velocity of light. But the difficulties interposed by spherical and chromatic aberration had arrested progress in that direction until, in 1655, Huygens, working with his brother Constantijn, hit upon a new method of grinding and polishing lenses.

The lizards look like geckos and they live in a nest or bubble that is covered by slime. 104. 1 : failure of a mirror, refracting surface, or lens to produce exact point-to-point correspondence between an object and its image. The use of mirrors instead of lenses was another way to avoid chromatic aberration. Another obvious inference from the necessary imperfection of optical images is the uselessness of attempting anything like an absolute destruction of spherical aberration. | Meaning, pronunciation, translations and examples If the surrounding aether is thereby disturbed, the waves of light arriving from the stars will partake of its movement; the ascertained phenomena of the astronomical aberration of light show that the rays travel to the observer, across this disturbed aether near the earth, in straight lines. 1. variable noun An aberration is an incident or way of behaving that is not typical. cit.

It has been in the past a source of much perplexity to observers of transits, but is now understood to be a result of irradiation, produced by the atmosphere or by the aberration of the telescope. Examples of Aberration in a sentence. If the path is to be unaltered by the motion of the aether, as the law of astronomical aberration suggests, this must differ from fds/V by terms not depending on the path - that is, by terms involving only the beginning and end of it.

L. Not very long after the disappearance of serfdom in the most advanced communities comes into sight the new system of colonial slavery, which, instead of being the spontaneous outgrowth of social necessities and subserving a temporary need of human development, was politically as well as morally a monstrous aberration. sentence examples. Its original use was the determination of geographical latitudes in the field work of geodetic operations; more recently it has been extensively employed for the determination S of variation of latitude, at fixed stations, under the auspices of the International Geodetic Bureau, and for the astronomical determination of the constant of aberration. His memorable discovery of the aberration of light (see Aberration) was communicated to the Royal Society in January 1729 (Phil. In a plane containing the image point of one colour, another colour produces a disk of confusion; this is similar to the confusion caused by two " zones " in spherical aberration. In general, we may say that aberration is unimportant when it nowhere (or at any rate over a relatively small area only) exceeds a small fraction of the wavelength (X). Some polyamorists argue that, since many other cultures embrace the idea of multiple partners, monogamy is an aberration. The total aberration of two or more very thin lenses in contact, being the sum of the individual aberrations, can be zero. With this mineral also spherical and chromatic aberration are a fraction of that of a glass lens, but double refraction, which involves a doubling of the image, is fatal to its use. deviation from truth or moral rectitude. Hence for the rain to centrally traverse the tube, this must be inclined at an angle BAD to the vertical; this angle is conveniently termed the aberration due to these two motions. 2 : unsoundness or disorder of the mind.

In Bode's Jahrbuch (1776-1780) he discusses nutation, aberration of light, Saturn's rings and comets; in the Nova acta Helvetica (1787) he has a long paper "Sur le son des corps elastiques," in Bernoulli and Hindenburg's Magazin (1787-1788) he treats of the roots of equation and of parallel lines; and in Hindenburg's Archiv (1798-1799) he writes on optics and perspective. Rudolf guides Santa's sleigh with the biological aberration of a red, glowing nose capable of penetrating thick fog? If it were desired to use an angular aperture so large that the aberration according to (13) would be injurious, Rowland points out that on his machine there would be no difficulty in applying a remedy by making v slightly variable towards the edges. The application of this observation to the phenomenon which had so long perplexed him was not difficult, and, in 1727, he published his theory of the aberration of light - a corner-stone of the edifice of astronomical science. Aberration definition: An aberration is an incident or way of behaving that is not typical . The lower surface of the slip causes undercorrection on being traversed by the pencil, with over-correction when it leaves it; and since the aberration of the surface lying farthest from the object, i.e. Compared to previous Rebel lenses, the T2i lens has increased sharpness and decreased chromatic aberration. Aberration is an EP by the Oakland, California band Neurosis. 2.

Asker, ABERRATION IS ALWAYS USED IN 10 sentences 1. Find more ways to say aberration, along with related words, antonyms and example phrases at Thesaurus.com, the … Newton was led by this reasoning to the erroneous conclusion that telescopes using refracting lenses would always suffer chromatic aberration. in lenses or mirrors or a series of them, may be defined as the non-concurrence of rays from the points of an object after transmission through the system; it happens generally that an image formed by such a system is irregular, and consequently the correction of optical systems for aberration is of fundamental importance to the instrument-maker. These are: (I) chromatic aberration, (2) spherical aberration and (3) astigmatism (see Aberration). We may suppose the aperture (a) constant, and inquire into the operation of an increasing aberration; or we may take a given value of c (i.e. , 2. noun [ C or U ] formal us. The second aberration which must be removed from microscope objectives are the chromatic. Bradley recognized the fact that the experimental determination of the aberration constant gave the ratio of the velocities of light and of the earth; hence, if the velocity of the earth be known, the velocity of light is determined. The aberration is here unsymmetrical, the wave being in advance of its proper place in one half of the aperture, but behind in the other half. If, by these methods, a point in the optic axis has been freed from aberration, it does not follow that a point situated only a very small distance from the optic axis can also be represented without spherical aberration.
