Aberration balance in error functions calculated analytically
نویسنده
چکیده
If the monochromatic error function of optical systems is computed analytically by means of aberration coefficients, certain intermediate results of this computation can be used for the investigation of the aberration balance. For the analysis of local minima resulting from optimization, a new automatic technique has been developed that groups together monochromatic aberrations having a large mutual compensation of their effect on the error function. Criteria are proposed to evaluate the quality of aberration balance. Present experience suggests the existence of a correlation between the quality of the pattern of aberration balance and the value of the error function.

Reduction of the quality of the image formed by an optical system is a function of different parameters such as lens aberrations, CCD digitization errors, and the errors of system assembling. Assembling errors usually consist of two types: 1) the prism error, which is the error of non-orthogonality of the optical axis and the image plane 2) the de-centering error, which is error of not passing ...
متن کاملRefractive error and monochromatic aberrations in Singaporean children
Higher order optical aberrations were measured in 273 cyclopleged Singaporean school children using a Bausch and Lomb Zywave aberrometer, with 268 of these subjects also undergoing corneal topography measurements (Tomey TMS 2 system). Subjects with low myopia (> -3.00 to -0.50 D) showed slightly, but significantly, less positive levels of spherical aberration than other refractive error groups....

In this paper, a dc Josephson junction between two singlet superconductors (d-wave and s-wave) with arbitrary reflection coefficient has been investigated theoretically. For the case of high Tc superconductors, the c-axes are parallel to an interface with finite transparency and their ab-planes have a mis-orientation. The physics of potential barrier will be demonstrated by a transparency coeff...
متن کاملFinite conjugate spherical aberration compensation in high numerical-aperture optical disc readout.
Spherical aberration arising from deviations of the thickness of an optical disc substrate from a nominal value can be compensated to a great extent by illuminating the scanning objective lens with a slightly convergent or divergent beam. The optimum conjugate change and the amount and type of residual aberration are calculated analytically for an objective lens that satisfies Abbe's sine condi...

Objective: People with Anterior Cruciate Ligament (ACL) reconstruction need to have almost automatic postural control to focus on their athletic skills. Continuous cognitive task is a method for removing attention from postural control. The effects of continuous cognitive task on postural control of people with ACL reconstruction has been assessed by laboratory tools; however, its effect using ...
