X resolution
X resolution is a measure of the number of pixels or data points along the horizontal axis of an image or display. It quantifies the level of detail that can be displayed horizontally, representing...
x-radiography
Radiography using the emission of x-rays to form an image of the structure penetrated by the radiation.
x-ray analysis
The series of processes used to identify and evaluate crystal structure by using crystalline solids to diffract x-rays. In the Laue method, radiation of a wide range of wavelengths is transmitted by...
x-ray astronomy
The study of the celestial bodies, relative to x-ray emission. Satellites launched to study x-ray sources have revealed many new classes of galactic and extragalactic sources, as well as the...
x-ray detector
One of various types of fluorescent screens used to detect x-ray radiation. Photographic film is mildly sensitive to x-rays, but much more sensitive to light. Hence, in photographing x-ray...
x-ray image intensifier
An image intensifier that consists of an evacuated tube with a large input phosphor screen at one end. The phosphor screen is in contact with a light-sensitive photocathode that emits electrons....
x-ray micrography
->
microradiography
Radiographic recording and enhancement of the micoscopic details within the structure of thin specimens at a high magnification. Also known as x-ray micrography
x-ray microprobe analysis
The method of acquiring characteristic x-ray spectra from microscopic samples by use of the combination of a scanning electron microscope and x-ray spectroscopy.
x-ray optics
The study of the physics of x-rays, where the x-rays exhibit properties similar to those of lightwaves. Also called Roentgen optics.
x-ray phase contrast microscopy
Used for high-resolution surface study with subnanometer resolution. XRIM uses interfacial phase contrast with application of hard x-rays over elementary surface structures availing the observation...
x-ray shadow microscope
->
projection x-ray microscope
A microscope that uses an extremely fine x-ray focal point to produce an enlarged photographic image of a sample. Also known as an x-ray shadow microscope.
x-ray source
A material or system that emits x-rays.
x-ray streak camera
A diagnostic instrument that uses a photocathode design to see a broad range of x-ray radiation by streaking the photographic image continuously in time. It produces time- and space-resolved...
x-ray tube target
Also known as an anticathode. An electrode or electrode section that is focused upon by an electron beam and that emits x-rays.
XEG
x-ray emission gauge
xenon arc
The arc formed when the rare gas xenon is excited electrically and emits a brilliant white light. Xenon is used to fill electronic and stroboscopic flashlamps, and also large discharge tubes for...
