  2. Millimeter wave scanner - Wikipedia

    en.wikipedia.org/wiki/Millimeter_wave_scanner

    Millimeter wave scanners should not be confused with backscatter X-ray scanners, a completely different technology used for similar purposes at airports. X-rays are ionizing radiation , more energetic than millimeter waves by more than five orders of magnitude , and raise concerns about possible mutagenic potential.

  3. X-ray optics - Wikipedia

    en.wikipedia.org/wiki/X-ray_optics

    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.

  4. Shoe-fitting fluoroscope - Wikipedia

    en.wikipedia.org/wiki/Shoe-fitting_fluoroscope

    The x-ray tube was removed to render the apparatus harmless before being put on public display, due to the possible risk of radiation burn or other health problems if it were switched on. The risk of radiation burns to extremities was known since Wilhelm Röntgen 's 1895 experiment, but this was a short-term effect with early warning from ...

  5. X-ray microscope - Wikipedia

    en.wikipedia.org/wiki/X-ray_microscope

    An X-ray microscopy image of a living 10-days-old canola plant [1]. An X-ray microscope uses electromagnetic radiation in the X-ray band to produce magnified images of objects. . Since X-rays penetrate most objects, there is no need to specially prepare them for X-ray microscopy observatio

  6. Telescopic sight - Wikipedia

    en.wikipedia.org/wiki/Telescopic_sight

    The scope base is the attachment interface on the rifle's receiver, onto which the scope rings or scope mount are fixed. Early telescopic sights almost all have the rings that are fastened directly into tapped screw holes on the receiver, hence having no additional scope base other than the receiver top itself.

  7. Sight (device) - Wikipedia

    en.wikipedia.org/wiki/Sight_(device)

    Mark III free gun reflector sight mk 9 variant. Another type of optical sight is the reflector (or "reflex") sight, a generally non-magnifying optical device that allows the user to look through a glass element and see a reflection of an illuminated aiming point or some other image superimposed on the field of view. [7]

  8. Diffractometer - Wikipedia

    en.wikipedia.org/wiki/Diffractometer

    There are several types of X-ray diffractometer, depending on the research field (material sciences, powder diffraction, life sciences, structural biology, etc.) and the experimental environment, if it is a laboratory with its home X-ray source or a Synchrotron. In laboratory, diffractometers are usually an "all in one" equipment, including the ...

  9. Soft X-ray microscopy - Wikipedia

    en.wikipedia.org/wiki/Soft_x-ray_microscopy

    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.
