If this diffraction grating is exposed to white light, because of interference, the white light is dispersed in a direction perpendicular to the grooves, and light components of specific wavelengths are reflected only in specific directions.
These diffraction gratings have achieved several milestones, such as the world's largest dimensions, a groove density reproducibility one order higher than that of conventional gratings, a maximum diffraction efficiency of 98%, and high damage resistance.
Unlike pickup lenses for CD and DVD players, incorporating simple diffractive optical elements into SLR camera lenses results in the generation of stray light.
If an antenna is set up in an application and the type and radiation pattern is not known, the tagged items might not be read or be affected by absorption, diffraction, reflection, and refraction.
While the sample is two-dimensionally scanned, the intensity distribution of X-rays that are elastically scattered forward at each point(coherent diffraction pattern) is measured with an X-ray charge coupled device(CCD) detector.
In other words, RF waves sent from the reader/antenna to the tag collide with objects or other RF waves causing refraction, diffraction, absorption, null zones, or extended read zones.
Typically, X-rays are directed from one side of the multi-well plate, pass through the plate and crystal and out the opposite side of the plate, where the diffraction data are collected on an X-ray sensitive detector.
This paper presents results from modeling RF propagation in a mine using Wireless InSite's Uniform Theory of Diffraction(UTD) ray tracing code to portray a communications system within a mine environment.
We can acquire stable images with spatial resolution close to the diffraction limit. Even with a 30cm aperture, for example, it can provide continuously high-resolution images covering the range from near-ultraviolet to visible light equivalent to the Subaru Telescope at its best.
By engineering the elimination of major sources of diffraction, Paradigm loudspeakers achieve superior resolution over a wider radiating area, with less distortion and more detail.
From the 2000s, however, various super-resolution fluorescence microscopes have been developed with the aim of attaining a spatial resolution that exceeds the diffraction limit. This has led to a spatial resolution of 100 nm or less being achieved.
