Research output: Contribution to journalArticlepeer-review


In this paper, the problem of phase reconstruction from magnitude of multidimensional band-limited functions is considered. It is shown that any irreducible band-limited function f(z1...,zn), zi ε{lunate} C, i=1, ..., n, is uniquely determined from the magnitude of f(x1...,xn): | f(x1...,xn)|, xi ε{lunate} R, i=1,..., n, except for (1) linear shifts: i(α1z1+...+αn2n), β, αiε{lunate}R, i=1,..., n; and (2) conjugation: f*(z1*,...,zn *).
