Meanings of speckle patterns in anglès

This new image illustrates the similarity between the speckle patterns around each point.

When a coherent beam illuminates spatially disordered particles, speckle patterns are formed due to interference of the scattered light waves.

While the amplitude of the speckles follows a Gaussian distribution, the autocorrelation of the speckle patterns tracks that of the system point spread function.

Speckle patterns from biological tissues using synchrotron phase contrast X-ray imaging can provide functional information about micro-scale morphological structures of the tissues.
