Applications of Diffraction and Interference of Light

By:

Karen Cooper


Scanning Tunneling Microscopy


Past

  • Gave scientists the ability to explore and manipulate solid surfaces on the size scale of atoms.

  • Helped discover fullerenes- spherical carbon molecules.


Quantum Corrals . N.d. IBM Almaden Research Cente. N.p., n.d. Web. 16 Mar. 2011. <http://www.almaden.ibm.com/vis/stm/>.


Present

  • Detects the flow of electrons

  • industrial and fundamental research to obtain atomic-scale images of metal surfaces


Slippery. 2005. Scanning Tunneling Microscope. N.p., n.d. Web. 16 Mar. 2011. <http://www.umsl.edu/ ~fraundorfp/stm97x.html>.


Future

  • To allow people to bring a "specimen" to a scanned probe microscope lab, put on a head-set designed for virtual reality, and stand among friends on a landscape of molecules resting on the specimen's surface. Every few seconds, the surface will ripple a bit, as the scanning probe tip passes by.


Holograms


  • Holography involves two basic steps: (1) creating a hologram and (2) illuminating the hologram to display the image.

Past

  • originally a sci-fi concept back when Star Wars previewed such technology

  • electron microscopy

Present

  • Used in credit cards to prevent counterfeiting

  • Appear in advertising displays, artwork, product packaging, and jewelry

  • Used to detect flaws in tires, lenses, airplane wings, and other products

  • Used in lasers and electron microscopy

Future

  • 3D motion hologram for TVs

  • 3D holographic projectors for phones

  • Holographic 3D movies

  • holographic gaming

Spectroscopy


  • Began work with Sir Isaac Newton(late 1600’s)


Past

  • Used to determine what chemical elements are in a star

  • Used to study radio waves


Present

  • Reveal the speed and direction of stars

  • Used to learn more about a material’s composition or structure

  • Used to obtain images of tissues inside a body


Future

  • detection in clinical chemistry

  • metabolic studies and continuous monitoring

  • detection of lower concentrations of biological compounds


Astronomy


  • Astronomers observe the sky with telescopes of different kinds that gather not only visible light but also invisible forms of energy, such as radio waves.


Past

  • Used in telescopes to detect visible light and other forms of radiation emitted from celestial objects

  • Used to tell how dense an object (such as the Moon) is


Present

  • Radio astronomy

  • Telescopes- produces “pictures” of astronomical objects

  • Used to reveal the speed and direction of a star


Future

  • Improve radio astronomy

  • Improve modern astronomical observation

  • Predict the future structure of the universe
