X-ray phase-contrast imaging at 100 keV on a conventional

X-ray grating interferometry is a promising imaging technique sensitive to attenuation, refraction and scattering of the radiation. Applications of this technique in the energy range between 80 and 150 keV pose severe technical challenges, and are still mostly unexplored. Phase-contrast X-ray

GRATINGS - New holographic gratings look at the cosmos

In many applications, such a grating can achieve higher diffraction efficiencies than classical surface-relief gratings that diffract light by the presence of modulated surface structure. The ability to make complex VPH grating structures-impossible with surface-relief gratings-allows the creation of new concepts for astronomical spectrographs.

Gratings - ZEISS

A diffraction grating is a periodically structure of subsequent most evenly spaced grating lines. Those grooves or opaque lines diffract the incident light depending on its periocity and microstructure. Depending on the light's incidence angle, rainbow-colored patterns are discernible on a projection surface behind a transmission or reflection

Development of Ultra-Low Noise, High Sensitivity Planar

In this reporting period, we have continued to make a significant progress towards the program goals. We have designed, fabricated and characterized several metal grating coupled bound-to-miniband (BTM) and step- bound-to-miniband (SBTM) transition QWIPs on the GaAs ad InP substrates for 8-12 microns focal plane arrays staring infrared sensor applications.

When Sand-Slithering Snakes Behave Like Light Waves

When Sand-Slithering Snakes Behave Like Light Waves

Snakes slithering across the desert sand at night can encounter obstacles such as plants or twigs that alter the direction of their travel. While studying that motion to learn how limbless animals control their bodies in such environments, Georgia Tech researchers discovered that snakes colliding with an obstacle behave much like light waves encountering an optical diffraction grating.

US20080317401A1 - Optic fiber bragg grating sensor

The optic fiber Bragg grating (FBG) sensor comprises of an elastic circular diaphragm and one or two FBG attached to the bottom surface of the elastic circular diaphragm. Two ends of the FBG are connected to an optic fiber for signal transmission. The FBG sensor readouts are independent of temperature fluctuation. The FBG sensor mechanism according to the present invention may be applied for

Why does increasing the number of slits for a diffraction

Could anyone in simple terms explain to me how the peaks are narrower as the number of slits increases in a diffraction grating? Note i've only come across double slit diffraction and was just introduced to this recently, and the explanation by hyperphysics is a bit confusing with formula.
