Abstract
Commencing from a projection-operator description of N-beam diffraction, th e mathematical basis for the recovery of phase and amplitude information fr om a three-beam convergent-beam electron diffraction pattern is given for b oth the centrosymmetric and noncentrosymmetric cases. The algebra is availa ble in Mathematica Notebook form from the URL ftp://ftp.physics.uwa.edu.au/ pub/EMC/3BeamAlgebra.nb.
