This paper gives a theoretical basis for calculating Fraunhofer diffra
ction patterns of arbitrary polyhedron particles. It is shown that thi
s solution can be used for calculating a scatter matrix adapted to the
particle shape in a straightforward manner. Some simulations were mad
e to show the difference between the size distribution by volume obtai
ned with a scatter matrix for spheres and with that for the appropriat
e shape. Finally, some experimentally measured signatures from platele
ts and rods are evaluated in order to show that the spherical equivale
nt diameter could be accurately retrieved.
