A processing method for rough cutting hourglass worm on general NC lathe
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2019 The manufacturing method of two spatial-orthogonal rotary axis linkage is usually used to cut hourglass worm. However, the traditional processing method of roughing tooth groove depends on the special machine, specific tool, and its processing efficiency

Birefringent optofluidic gratings
Optics Express, 2020 A set of parallel microfluidic channels behaving as a diffraction grating operating in the Raman-Nath regime has been fabricated and studied. The diffraction efficiency of such structure can be tuned by selecting a liquid with a particular refractive index and/or optical anisotropy.

Full field phase imaging using a harmonically matched diffraction grating pair based homodyne quadrature interferometer [PDF]
, 2007 In this letter, the authors present a novel quadrature interferometry method based on the use of a harmonically matched shallow grating pair. Unlike a simple beam splitter or single shallow grating, the grating pair can confer a nontrivial interference ...

Mask pattern transferred transient grating technique for molecular-dynamics study in solutions [PDF]
, 2004 We have developed a mask pattern transferred transient grating (MPT-TG) technique by using metal grating films. Transient thermal grating is generated by an ultraviolet light pattern transfer to nitrobenzene in 2-propanol solution, and the subsequent ...

Compact focusing grating couplers for silicon-on-insulator integrated circuits [PDF]
, 2007 —We report experimental results on compact and broadband focusing grating couplers, both in silicon-on-insulator (SOI) and gold on SOI. An eight-fold length reduction of the coupling structure from fiber to photonic wire in SOI, as com-pared to a linear ...
