mathematical solution of the inverse problem of diffraction in the
Fraunhofer regime. After the first publication [1] the Differential Fourier
Holography was successfully applied in many experiments to obtain
amplitude and phase information about two-dimensional (2D) images. In
this article we demonstrate numerically the possibility to apply the DFH
also for investigation of unknown 3D Objects. The first simulation is made
for a double-spiral structure plus a line as a reference object.

The novel instrument produces simultaneously two sets of mirror-symmetric spectra, and provides large dispersion, high spectral and 1D spatial resolution with a variable magnification.
