Diffraction Gratings Ruled and Holographic - HORIBA

Diffraction Gratings Ruled and Holographic - HORIBA

Diffraction gratings are manufactured either classically with the use of a ruling engine by burnishing grooves with a diamond stylus, or holographically with the use of interference fringes generated at the intersection of two laser beams 1.. Classically ruled gratings may be planar or concave and possess grooves, each parallel with the next.

Grating-box test: A testing method for filling performance

An alternative testing method named “grating-box test” is proposed in this paper to evaluate the filling performance of self-compacting cementing materials in granular packs. In the grating-box test, the normalized h 2 (h 2 N) is selected as an indicator to evaluate the filling performance of different SCM, and its value is found to

A small amount of narrowband optical feedback can stabilize the output spectrum of a laser diode. A typical application of volume Bragg gratings is the wavelength stabilization of lasers, most often of laser that purpose, a grating is usually placed not directly in front of the laser diode, but after a collimating lens (at least a fast axis collimator).

Grating can also come in 4 feet ( cm) or 2 feet (61 cm) x 8 feet ( cm) panels which are often used for decks on bridges, footbridges and catwalks. Other panel sizes may also be available. Grating can be made of different materials like steel, aluminum, fiberglass. Fiberglass grating is also known as FRP grating.

Waveguide sub‐wavelength structures: a review of

Grating couplers exhibit a limited bandwidth. From the grating equation 6 it is apparent that the radiation angle changes with wavelength. In fact, for large angular variations comparable to the numerical aperture of the fiber (which has to be kept at a fixed angle over the grating) coupling to the fiber is dramatically reduced.

The thermal conductivities at one point are not equal in all directions for anisotropic materials. The technique of double skin facade has been successfully applied in many building designs. The application of combining building envelope of anisotropic materials and double skin facade was proposed to avoid its disadvantage.
