In a perfect optical system in the classical theory of optics, rays of light proceeding from any object point unite in an image point; and therefore the object space is reproduced in an image space. The introduction of simple auxiliary terms, due to Gauss, named the focal lengths and focal planes, permits the determination of the image of any object for any system. The Gaussian th… WebJan 17, 2013 · Field Curvature, also known as “curvature of field” or “Petzval field curvature”, is a common optical problem that causes a flat … WebOptical aberrations are deviations from a perfect, mathematical model.
