0 present participle of diffract --
1 to break up light or sound waves by making them go through a narrow space or across an edge --
For light, we can often neglect one direction if the diffracting object extends in that direction over a distance far greater than the wavelength.
For light, we can often neglect one dimension if the diffracting object extends in that direction over a distance far greater than the wavelength.
In order to gain energy spectrum information, a diffracting crystal may be used to separate the different photons.
In white-beam topography, all misoriented crystallites will be diffracting simultaneously (each at a different wavelength).
Highly ordered, strongly diffracting materials - like minerals or semiconductors - are generally unproblematic, whereas e.g. protein crystals are particularly challenging for topographic imaging.
Upon sample rotation, these will disappear, and other crystallites will appear in the new topograph as strongly diffracting.
They are artifacts caused by light diffracting around the support vanes of the secondary mirror.
These coefficients are then used to calculate the field strength and phase for each direction away from the diffracting point.
