Aberration Structure of Spot of Dispersion in the Image of Point at the Decentering Elements of the Optical System

Desentering is named displacement of elements of the optical system of transverse optical axis. At the decentering of elements of the optical system its axial symmetry is violated. The structure of spots of dispersion in the image of points of object is thus violated. It is comfortably to execute the analysis of structure of representing points in area of primary aberrations (aberrations of Zeydelya).It is shown that at the decentering of elements of the optical system in the diffraction image of points, which do not lie on an optical axis, new aberration with the meridional and sagyttal constituents appears along with the known primary aberrations (coma, astigmatism, dystorsia).The aberration spot described by the got expression has the appearance of circle, the radius of which is determined by not only the coordinate on the pupil of the optical system but also by the value of the decentering
