Applied Optics, 1975
A new instrument, the aberration generator, has been developed for introducing precise amounts of aberration into an optical wavefront. Piston error, wavefront tilt, defocus, spherical aberration, coma, and astigmatism can be generated either individually or in combination. The instrument can be used to study the effects of aberrations on image quality

Muscle & Nerve, 1990
AbstractAlthough great empasis is placed on providing a satisfactory conduit for regeneration of peripheral axons after nerve repair, the quality of functional restoration is influenced as much by the quality as the quantity of axonal regeneration. Misdirected regeneration is so commonly encountered that motor axons appear to enter and regenerate to ...

Skew aberration: a form of polarization aberration
Optics Letters, 2011We define a new class of aberration, skew aberration, which is a component of polarization aberration. Skew aberration is an intrinsic rotation of polarization states due to the geometric transformation of local coordinates, independent of coatings and interface polarization.

Obstetrics and Gynecology Clinics of North America, 1992
With the emergence of an understanding of the processes at the cellular level that control the differentiated functions of tissues and eventually manifest as the developmental sequence in the whole animal, it is possible to describe pubertal aberrations in terms that are at once grounded in fundamental concepts of cellular biology and of practical ...

Lens Aberrations and Aberration Correction
2016Aberrations in a lens refer to departure from the point-to-point imaging prescribed by the paraxial equation introduced in Chap. 6.

Using simple ray tracinig technliques presented in Chapter 6, we demonstrate that a general ray is not focused to the position predicted by paraxial theory. The aberration displayed is spherical aberration. Two methods of measuring aberration: the use of optical path difference to characterize wavefront aberration.
