Pincushion Distortion Aberrations at Shani Amy blog

Pincushion Distortion Aberrations. The two most prevalent types of distortion, positive and negative (often termed pincushion and barrel, respectively), can often be present in very sharp images that are otherwise corrected for spherical, chromatic, comatic, and astigmatic aberrations. Pincushion distortion used for this purpose since they are made up of terms that are of the same form as the types of aberrations often observed in optical tests (zernike, Negative, barrel distortion, where points in the fov appear too close to the center; Causes, corrections, and optics basics. Learn about lens aberrations, correction techniques, and future technologies. The barrel and pincushion distortions below can be readily seen in the image formed. Other than distortions from lens imperfections, certain distortions occur from the geometry of the lens. Barrel distortion results when the magnification decreases with distance away from axis, while pincushion results is from increasing magnification. A third class of aberrations, commonly seen in stereo microscopes that have zoom lens systems, is geometrical distortion, which includes both barrel. Both are induced by a slight misshape. In simple lenses, there are two main types of distortion:
