DESCRIPTION:We outline some aspects of deterministic phase ret
 rieval\, namely the reconstruction of wavefield ph
 ase from intensity measurements. Attention is focu
 sed on methods employing the so-called transport-o
 f-intensity equation\, this being the continuity e
 quation associated with the paraxial (parabolic) e
 quation.  Applications in electron microscopy\, x-
 ray imaging\, neutron optics and superfluidity wil
 l be discussed.  We will also briefly outline the 
 importance of topological defects in the phase\, n
 amely screw dislocations and domain walls\, on the
  question of deterministic phase retrieval.
