  2. X-ray specs - Wikipedia

    en.wikipedia.org/wiki/X-ray_specs

    X-ray specs. X-ray specs or X-ray glasses are an American novelty item, purported to allow users to see through or into solid objects. In reality, the spectacles merely create an optical illusion; no X-rays are involved. The current paper version is sold under the name "X-Ray Spex"; a similar product is sold under the name "X-Ray Gogs".

  3. Miller index - Wikipedia

    en.wikipedia.org/wiki/Miller_index

    Miller indices form a notation system in crystallography for lattice planes in crystal (Bravais) lattices . In particular, a family of lattice planes of a given (direct) Bravais lattice is determined by three integers h, k, and ℓ, the Miller indices. They are written ( hkℓ ), and denote the family of (parallel) lattice planes (of the given ...

  4. X-ray lithography - Wikipedia

    en.wikipedia.org/wiki/X-ray_lithography

    X-ray lithography is a process used in semiconductor device fabrication industry to selectively remove parts of a thin film of photoresist. It uses X-rays to transfer a geometric pattern from a mask to a light-sensitive chemical photoresist , or simply "resist," on the substrate to reach extremely small topological size of a feature.

  5. X-ray optics - Wikipedia

    en.wikipedia.org/wiki/X-ray_optics

    X-ray optics. X-ray optics is the branch of optics that manipulates X-rays instead of 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 ...

  6. X-ray - Wikipedia

    en.wikipedia.org/wiki/X-ray

    X-rays (or rarely, X-radiation) are a form of high-energy electromagnetic radiation. In many languages, it is referred to as Röntgen radiation, after the German scientist Wilhelm Conrad Röntgen, who discovered it in 1895 [1] and named it X-radiation to signify an unknown type of radiation.

  7. X-ray laser - Wikipedia

    en.wikipedia.org/wiki/X-ray_laser

    X-ray laser. An X-ray laser can be created by several methods either in hot, dense plasmas or as a free-electron laser in an accelerator. 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 ...

    Natural X-ray sources: Astrophysical X-ray source, as viewed in X-ray astronomy. X-ray background. Naturally occurring radionuclides. Artificial X-ray sources. Radiopharmaceuticals in radiopharmacology. Radioactive tracer. Brachytherapy. X-ray tube, a vacuum tube that produces X-rays when current flows through it.

  9. POV-Ray - Wikipedia

    en.wikipedia.org/wiki/POV-Ray

    AGPL-3.0-or-later [5] Website. www.povray.org. The Persistence of Vision Ray Tracer, most commonly acronymed as POV-Ray, is a cross-platform ray-tracing program that generates images from a text-based scene description. It was originally based on DKBTrace, written by David Kirk Buck and Aaron A. Collins for Amiga computers.
