In geometric optics, distortion is a deviation from rectilinear projection; a projection in which straight lines in a scene remain straight in an image.It is a form of optical aberration that may be distinguished from other aberrations such as spherical aberration, coma, chromatic aberration, field curvature, and astigmatism in a sense that these impact the image sharpness without changing an ...
Unlike conventional prescription glasses, pinhole glasses produce an image without the pincushion effect around the edges (which makes straight lines appear curved). While pinhole glasses are claimed to be useful for people who are both near- and far-sighted, they are not recommended [citation needed] for people with over 6 diopters of myopia.
The reverse, in which the perimeter is magnified more than the center, is known as "pincushion distortion" (figure 3b). This effect is called lens distortion or image distortion, and there are algorithms to correct it. Systems free of distortion are called orthoscopic (orthos, right, skopein to look) or rectilinear (straight lines). Figure 4
The globe effect, also known as rolling ball effect, is an optical illusion which can occur with optical instruments used visually, in particular binoculars or telescopes. If such an instrument is rectilinear , or free of rectilinear distortion , some observers get the impression of an image rolling on a convex surface when the instrument is ...
Luigi Mangione, the suspect accused of fatally shooting UnitedHealthcare CEO Brian Thompson in New York City last week, was not a customer of the private health insurer, but police say he had ...
Syria's brutal civil war rekindled suddenly after 13 years, with rebels staging a shock offensive that forced long-time dictator Bashar al-Assad to flee to Russia.
