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.

Nano-Focusing and Leveling System Based on Improved Phase Analysis
IEEE Photonics Journal, 2016 A nano-focusing and leveling system (FLS) based on improved phase analysis is proposed to measure the wafer height in lithography. Different from traditional methods, this paper applies a grating-based mark to conduct the measurement according to the ...

Applied Sciences, 2019 A subwavelength fine-structured silicon−gold metagrating was designed for realizing mid-infrared (mid-IR) narrowband absorbers. The metagrating consisted of a silicon grating on the stack of a gold film and a quartz substrate.

Facilitation of Luminance Grating Detection by Induced Gratings
Vision Research, 1996 Grating induction causes a homogeneous test field surrounded by sinewave gratings to possess an induced counterphase grating [McCourt M. E. (1982). Vision Research, 22, 119]. There is currently no consensus about the stage of visual processing at which illusory phenomena such as simultaneous brightness contrast are signaled.

Scanning effects in coherent fourier scatterometry [PDF]
Journal of the European Optical Society-Rapid Publications, 2012 Incoherent Fourier Scatterometry (IFS) is a successful tool for high accuracy nano-metrology. As this method uses only far field measurements, it is very convenient from the point of view of industrial applications.

Theoretical Computer Science, 1994 This note gives a construction for a family of weak grates; that is, acyclic digraphs of logarithmic depth with this property: A superlinear number of pairs of vertices remain connected after removing any sufficiently small linear sized vertex set. The construction is based on one by Schnitger for acyclic digraphs with a similar property.

Interaction between luminance gratings and disparity gratings
Spatial Vision, 2004 It was shown from geometry and photographic measurement that the shading pattern for a sinusoidal corrugated surface of frequency f approximates to a luminance-defined grating of frequency f, 2f or f + 2f in specific relative phase. It was confirmed that a luminance grating modifies the appearance of a suprathreshold stereoscopic corrugated surface ...
