From memory, correlation length is the length during which the phase of the
electric field is preserved. It's typically computed by applying time (pulse
width)- frequency (converted to length) uncertainty principle.

Subject: [ccp4bb] X-ray photon correlation length
I always wondered - how is the X-ray photon correlation length defined
and where do I find it? This is not the interaction length, I assume.
So, to the physicists: How large is the 'X-ray photon correlation length'
for a given wavelength in a given material?
I had the impression that the term photon correlation refers
to the time correlation of the scattering such as in photon correlation
spectroscopy.
Best regards, BR
