Here we present measurements of irregular diffraction patterns for NO radicals colliding with rare-gas atoms that can be explained by the analytical Fraunhofer model. They reveal a hitherto ...

A laser beam is shone onto a variable rectangular aperture. The size of the hole determines the type of diffraction produces on the screen. Very small apertures produce Fraunhofer diffraction, and ...

Figure 3 shows the particle size distributions calculated by laser diffraction (Mastersizer 3000) using Mie Theory for RI values of 1.54 and 1.575. The result obtained using the Fraunhofer ...

But this approach is rarely used, and two approximations are introduced instead: the Fraunhofer approximation ... Figure 1: Coherent diffraction imaging in the far- and near-field.

Researchers at the Fraunhofer Institute for Applied Optics and Precision ... slightly different laser wavelengths are directed onto gratings at subtly different angles, so that diffraction combines ...

Laser diffraction is an ensemble particle-sizing technique ... via a deconvolution step. The Mie theory and the Fraunhofer approximation (of Mie theory) are used routinely. ISO 13320:2009 provides a ...

The Fraunhofer Institute for Solar Energy Systems (ISE ... Verifying and fine-tuning the approach To confirm and understand this effect, the team used X-ray diffraction to analyze structural changes, ...

A new technical paper titled “Resolution enhancement for high-numerical aperture extreme ultraviolet lithography by split pupil exposures: a modeling perspective” was published by researchers at ...

Researchers from Dutch research institute AMOLF and Germany's Fraunhofer Institute for Solar ... of the increased optical path length by the diffraction of grids themselves. This is the first ...
