Crystallogr., v.39 2006 ref is an X ray diffraction X ray diffraction ref WIDEANGLE X RAY DIFFRACTION THEORY VERSUS CLASSICAL DYNAMICAL THEORY by S.G. Podorov, A. Nazarkin, Recent Res. Devel. Optics, 7 2009 ISBN 978 81 308 0370 8 ref technique that is often used to determine the crystalline structure of polymer s. This technique specifically refers to the analysis of Bragg peak s scattered to wide angles, which by Bragg s law implies that they are caused by sub nanometer sized structures. Wideangle X ray scattering is the same technique as small angle X ray scattering SAXS only the distance from sample to the detector is shorter and thus diffraction maxima at larger angles are observed. Depending on the measurement instrument used it is possible to do WAXS and SAXS in a single run small and wideangle scattering, SWAXS . The technique is a time honored but a somewhat out of favor technique for the determination of degree of crystallinity of polymer samples. The diffraction pattern generated allows to determine the chemical composition or phase composition of the film, the texture of the film preferred alignment of crystallites , the crystallite size and presence of film stress. According to this method the sample is scanned in a wideangle X ray goniometer , and the scattering intensity is plotted as a function of the 2 angle. X ray diffraction is a non destructive method of characterization of solid materials. When X rays are directed in solids they will scatter in predictable patterns based upon the internal structure of the solid. A crystalline solid consists of regularly spaced atoms electrons that can be described by imaginary planes. The distance between these planes is called the d spacing ... more details

Notice the barrel distortion typical for fisheye lens es in the curvilinear image. While this example has been rectilinear corrected by software, high quality wide angle lens es are built with optical rectilinear correction. In photography , a rectilinear lens is a photographic lens that yields images where straight features, such as the walls of buildings, appear with straight lines, as opposed to being curved. In other words, it is a lens with little or no barrel or pincushion Image distortion distortion . At particularly wide angles, however, the rectilinear perspective will cause objects to appear increasingly stretched and enlarged as they near the edge of the frame. These types of lenses are often used to create forced perspective effects. The vast majority of video and still cameras use lenses that produce nearly rectilinear images. A popular alternative type of lens is a fisheye lens which produces a distinctly curvilinear, wide angle lens wide angled result.
