SUMMARY:Some aspects of deterministic phase retrieval - David Paganin\, Sc
 hool of Physics\, Monash University\, Australia

CONTACT:Edmund Ward
DESCRIPTION:We outline some aspects of deterministic phase retrieval\, nam
 ely the reconstruction of wavefield phase from intensity measurements. Att
 ention is focused on methods employing the so-called transport-of-intensit
 y equation\, this being the continuity equation associated with the paraxi
 al (parabolic) equation.  Applications in electron microscopy\, x-ray imag
 ing\, neutron optics and superfluidity will be discussed.  We will also br
 iefly outline the importance of topological defects in the phase\, namely 
 screw dislocations and domain walls\, on the question of deterministic pha
 se retrieval.
