The icon consists of a statue of Jesus, smiling and winking while pointing at onlookers with one hand and giving the thumbs-up sign with the other hand. Buddy Christ was later produced as an action figure and a bobblehead. [2] The image has since been turned into a popular Internet meme.
X-ray optics is the branch of optics dealing with X-rays, rather than visible light.It deals with focusing and other ways of manipulating the X-ray beams for research techniques such as X-ray diffraction, X-ray crystallography, X-ray fluorescence, small-angle X-ray scattering, X-ray microscopy, X-ray phase-contrast imaging, and X-ray astronomy.
This machine was manufactured by Adrian Shoe Fitter, Inc. circa 1938 and used in a Washington, D.C., shoe store. The shoe-fitting fluoroscope, also sold under the names X-ray Shoe Fitter, Pedoscope and Foot-o-scope, was an X-ray fluoroscope machine installed in shoe stores from the 1920s until about the 1970s.
Sub-MeV radiation from a nuclear explosion may be more important in (empty) space. Given this realization, during the 1960s [3] the U.S. military began to investigate whether military systems could be tested for their response to nuclear-weapon generated pulsed x-rays with flash x-ray machines. At the time these were fairly small, primarily ...
X-ray motion analysis is a technique used to track the movement of objects using X-rays.This is done by placing the subject to be imaged in the center of the X-ray beam and recording the motion using an image intensifier and a high-speed camera, allowing for high quality videos sampled many times per second.
The phrase "X-ray welding" also has an older, unrelated usage in quality control. In this context, an X-ray welder is a tradesperson who consistently welds at such a high proficiency that they rarely introduce defects into the weld pool, and are able to recognize and correct defects in the weld pool, during
An X-ray microscope uses electromagnetic radiation in the soft X-ray band to produce images of very small objects. Unlike visible light , X-rays do not reflect or refract easily, and they are invisible to the human eye.
This article describes the x-ray lasers in plasmas, only. The plasma x-ray lasers rely on stimulated emission to generate or amplify coherent, directional, high-brightness electromagnetic radiation in the near X-ray or extreme ultraviolet region of the spectrum, that is, usually from ~3 nanometers to several tens of nanometers (nm) wavelength.
