there is a vast number of publications about this, and each one will give you a different formula.
There is some physics behind the different methods, but it is not a straightforward procedure.
Most methods rely, however, on the analysis of Fourier coefficients.
Look at Kamminga&Delhez, J. Appl. Cryst 33 (2000) 1122 (for a recent work), and also at works by M. Wilkens (mostly of older dates) or T.Ungar (quite recent).
However, if you want to get reliable dislocation densities, you have to know that much about your dislocations that there is no sense any more to determine them by X-ray powder diffraction.
(perhaps an exteme statement).

Dear colleages,
Could any of you give the details about the procedure (equations, methods) to deduce the density of dislocatins from the lattice microstrains obtained from the Stokes and Wilson or variance or integral breadth methods.
Thanks in advance.
Sinverely yours,
Angel L.
