    • Aberration A partial alienation of reason. "Occasional aberrations of intellect.""Whims, which at first are the aberrations of a single brain, pass with heat into epidemic form."
    • Aberration (Astron) A small periodical change of position in the stars and other heavenly bodies, due to the combined effect of the motion of light and the motion of the observer; called annual aberration, when the observer's motion is that of the earth in its orbit, and daily or diurnal aberration, when of the earth on its axis; amounting when greatest, in the former case, to 20.4'', and in the latter, to 0.3''. Planetary aberration is that due to the motion of light and the motion of the planet relative to the earth.
    • Aberration The act of wandering; deviation, especially from truth or moral rectitude, from the natural state, or from a type. "The aberration of youth.""Aberrations from theory."
    • Aberration (Opt) The convergence to different foci, by a lens or mirror, of rays of light emanating from one and the same point, or the deviation of such rays from a single focus; called spherical aberration, when due to the spherical form of the lens or mirror, such form giving different foci for central and marginal rays; and chromatic aberration, when due to different refrangibilities of the colored rays of the spectrum, those of each color having a distinct focus.
    • Aberration (Physiol) The passage of blood or other fluid into parts not appropriate for it.
    • Aberration (Law) The producing of an unintended effect by the glancing of an instrument, as when a shot intended for A glances and strikes B.

    • n aberration The act of wandering away; deviation; especially, in a figurative sense, the act of wandering from the right way or course; hence, deviation from truth or moral rectitude.
    • n aberration In pathology: A wandering of the intellect; mental derangement.
    • n aberration Vicarious hemorrhage.
    • n aberration Diapedesis of blood-corpuscles.
    • n aberration Congenital malformation.
    • n aberration In zoology and botany, deviation from the type; abnormal structure or development.
    • n aberration In optics, a deviation in the rays of light when unequally refracted by a lens or reflected by a mirror, so that they do not converge and meet in a point or focus, but separate, forming an indistinct image of the object, or an indistinct image with prismatically colored edges. It is called spherical when, as in the former case, the imperfection or blurring arises from the form of curvature of the lens or reflector, and chromatic when, as in the latter case, there is a prismatic coloring of the image arising from the different refrangibility of the rays composing white light, and the consequent fact that the foci for the different colors do not coincide. Thus, in fig. 1, the rays passing through the lens L L near its edge have a focus at A, while those which pass near the axis have a focus at B; hence, an image formed on a screen placed at m m would appear more or less distorted or indistinct.
    • n aberration In astronomy, the apparent displacement of a heavenly body due to the joint effect of the motion of the rays of light proceeding from it and the motion of the earth. Thus, when the light from a star that is not directly in the line of the earth's motion is made to fall centrally into a telescope, the telescope is in reality inclined slightly away from the true direction of the star toward that in which the earth is moving; just as one running under a vertically falling shower of rain, and holding in his hand a long-necked flask, must incline its mouth forward if he does not wish the sides of the neck to be wetted. This phenomenon, discovered and explained by Bradley (1728), is termed the aberration of light, and its effect in displacing a star is called the aberration of the star. The annual aberration, due to the motion of the earth in its orbit, amounts to 20″.4 in the maximum; the diurnal aberration, due to the rotation of the earth, is only 0″.3 at most. See planetary aberration, below.

A fond desire which floats before our eyes;
With lurid aberration, feverish,--
We clutch the shadow which elusive, flies;
Though at our grasp the mocking fancy flees,
Hope still pursues and soothes realities.
"Hope." by Alfred Castner King

The first, high-order Adaptive Optics (hereafter “AO”), provides control and manipulation of the image by correcting the aberrations in the incoming stellar wave front caused by the Earth’s atmosphere.
A New High Contrast Imaging Program at Palomar Observatory
Small phase aberrations in the incoming stellar wave front, arising from imperfections in the AO optics or the coronagraphic optics, can lead to a pattern of speckles that litter the image in the focal plane (e.g.
A New High Contrast Imaging Program at Palomar Observatory
AO wave front sensor), e.g., small aberrations in the coronagraphic optics, as small as 1 nm occurring “downstream” of the wave front sensor.
A New High Contrast Imaging Program at Palomar Observatory
These optical aberrations translate directly to errors in the incoming stellar wave front.
A New High Contrast Imaging Program at Palomar Observatory
This subsystem actively senses phase aberrations in the coronagraph wave front, and provides centroid offsets to the Deformable Mirror to pre-compensate for these aberrations.
A New High Contrast Imaging Program at Palomar Observatory
These aberrations are the source of the quasi-static speckle noise, which greatly inhibits our ability to detect faint companions to nearby stars.
A New High Contrast Imaging Program at Palomar Observatory
The primary corrective optic in the new system is a 3388actuator deformable mirror (hereafter, “DM”), which will correct the wave front aberrations at high-spatial frequencies (the “tweeter”).
A New High Contrast Imaging Program at Palomar Observatory
However, the system will also make use of the original 241-actuator DM (the “woofer”) to correct the low-order aberrations.
A New High Contrast Imaging Program at Palomar Observatory
This system will eventually operate at the ∼1 Hz update rate, which is easily sufficient given that this subsystem aims to minimize the quasi-static wave front aberrations in the wave front which give rise to speckles with timescales of hundreds of seconds or longer (Hinkley et al. 2007).
