High order aberration definition
Webas either primary aberration or third order ray aberration or fourth order wave aberration depending upon context. In addition to their type, aberrations are often specified according to their order (third-order, fifth-order, etc.), though they are called primary, secondary etc sometimes. Moreover higher order aberrations introduce new types. WebA higher-resolution design for the same number of factors will, however, require more runs and so it is 'worse' than a lower order design in that sense. Resolution V designs for 8 factors Similarly, with a resolution V design, main effects would be confounded with four-factor (and possibly higher-order) interactions, and two-factor interactions ...

WebOptical aberrations are deviations from a perfect, mathematical model. It is important to note that they are not caused by any physical, optical, or mechanical flaws. Rather, they can be caused by the lens shape itself, or the placement of optical elements within a system, due to the wave nature of light.

WebI Higher Order Aberration Theory. This chapter discusses the higher order aberration theory and provides a connecting survey of the theories of Schwarzschild, Smith, and Herzberger from a modern point of view. This requires a modification of Schwarzschild's theory and the classification of connecting relations that were difficult to recognize.
A higher-order aberration is a distortion acquired by a wavefront of light when it passes through an eye with irregularities of its refractive components (tear film, cornea, aqueous humor, crystalline lens and vitreous humor). Abnormal curvature of the cornea and crystalline lens may contribute to the distortion … See more Higher-order aberrations are identified by the types of distortions acquired by a wavefront of light as it passes through your eye.
