Fibrous radial structure of speckle patterns in polychromatic light
Abstract:
A fibrous radial structure of speckle patterns produced at the far-field diffraction plane by various diffuse objects under illumination of polychromatic light is studied theoretically and experimentally by means of the spatial correlation function of the speckle intensity. It is shown that the fibrous radial structure of speckle patterns strongly depends on both the surface roughness of diffuse objects under illumination and the radial distance from the center of patterns at the far-field diffraction plane.

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...

X-ray Diffraction of Biological Samples
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal crystal...
