Sentence examples for aberration field from inspiring English sources

Longitudinal spherical aberration, field curvature, and distortion are computed at wavelengths of 486, 587, and 656 nm as a function of field angle in Fig. 12. Field curvature and astigmatism are almost the same for different DOFs.

Assuming such a system is well corrected for the lower-order field-dependent aberrations (field curvature and field-dependent astigmatism) one may imagine the possibility of incorporating static elements in the pupil conjugate plane which correct typical values of spherical aberration c(4,0), which is field-independent.

To probe the thickness and microstructure of GdO x films, low-voltage spherical aberration corrected field emission TEM (Cs-corrected FE-TEM) was performed.

The Zernike aberrations across field of view are also achieved to investigate the varying characteristics of off-axis aberrations.

Spatial warping then results with aberrations in field strength that can be caused by residual error in system calibrations and by the presence of materials such as dental implants, prostheses and even due to transitions between materials, for example, between tissue and air.

The present study provides the theory base for designing flat-field Schmidt optical systems, based on the wavefront aberration of Petzval field curvature, a mathematic model of the Petzval radius is setting up.

There is an irregular field aberration pattern, for each eye (subjects 1 and 4) with relatively low magnitude total RMS.

Subjects 1 and 4 present mild amounts of aberration over the field, with the plots for both subjects using the same color scale.

Using a variable low-order field aberration corrector in conjunction with an adaptive optics system might be an alternative to the multi-conjugated AO system proposed recently [ 61, 62].

In the second part of this study we report an investigation of the isoplanatic patch of the eyes of 4 subjects by sampling the wavefront aberration over 129 field points (14 degrees × 11.6 degrees).

The most common kind of aberration for bright-field microscopy is uneven illumination, a low frequency light intensity variation over the field-of-view.
