Diffraction gratings

Mathematical and Computational Methods in Photonics and Phononics, 2018
Recent progress in the techniques of manufacture of spectroscopic diffraction gratings is described. Three main topics are discussed in detail: (i) the mechanical ruling of gratings, and the way in which the mechanical aspects of the ruling process ...

Novel immersion grating, VPH grating and quasi-Bragg grating

SPIE Proceedings, 2006
We have successfully fabricated germanium immersion gratings with resolving power of 45,000 at 10 μm by using a nano precision 3D grinding machine and ELID (ELectrolytic In-process Dressing) method. However the method spends large amount of machine times.

Grating interferometers for producing large holographic gratings

Applied Optics, 1990
Methods for producing large holographic diffraction gratings are described. In particular, the advantages of using a grating interferometer illuminated with a noncollimated beam from either an extended monochromatic source or an extended polychromatic source are described along with some of the problems that arise and methods to solve them ...

Mechanisms of Grating Formation and Grating Materials

1986
In the following section, different mechanisms of light-induced changes of optical material properties are described. Often these changes are considered to be due to some specific material excitation (e.g., electron density, temperature). This is, however, a simplified description.

On the processing rate of gratings superimposed on gratings.

Acta physiologica et pharmacologica Bulgarica, 1988
Psychophysical and electrophysiological experiments suggest that visual image processing is effectuated successively as regard as its spatial frequency (SF) content, low SF-information being processed faster than high SF-information. In an investigation of the effect of exposure time on the detection threshold of a test grating superimposed on a high ...
