उदाहरण वाक्य

  1. In the above simulations with the 4 mm diameter disc the adjacent Fresnel zone has a width of about 77 �m.
  2. Random edge corrugation whose amplitude is of the same order as the width of that adjacent Fresnel zone reduces the Arago spot intensity.
  3. Composed of a series of discs centered about an origin, Fresnel zone plates are manufactured using laser pulses, which embed voids into reflective lens.
  4. This is caused by diffraction effects : for the best propagation, a volume known as the first Fresnel zone should be kept free of obstructions.
  5. "' David Sayre "'( March 2, 1924  February 23, 2012 ) was an American scientist, credited with the early development of Fresnel zone plates.
  6. Until now, resolutions of 30 nanometer are possible using the Fresnel zone plate lens which forms the image using the soft x-rays emitted from a synchrotron.
  7. If the diameter of the circular hole in the screen is sufficient to expose two Fresnel zones, then the amplitude at the center is almost zero.
  8. A zone plate consists of a set of radially symmetric rings, known as Fresnel zones, which alternate between interferes at the desired focus, creating an image there.
  9. Despite its weak reflectance ( R = 0.25?2 ? 2 at T = 1.3 ?10-4 K ), graphene has utility as a lens for Fresnel zone plates.
  10. He suggested to use the newly developed electron beam lithography apparatus at IBM to produce Fresnel zone plates, a type of X-ray lens now widely used in Synchrotron facilities.
