  An approach reported recently by Alexandrov et al. on optical scatter
imaging, termed digital Fourier microscopy (DFM), represents an adaptation of
digital Fourier holography to selective imaging of biological matter.
Holographic mode of recording of the sample optical scatter enables
reconstruction of the sample image. Form-factor of the sample constituents
provides a basis for discrimination of these constituents implemented via
flexible digital Fourier filtering at the post processing stage. Like in the
dark-field microscopy, the DFM image contrast appears to improve due to the
suppressed optical scatter from extended sample structures. In this paper, we
present theoretical and experimental study of DFM using biological phantom that
contains polymorphic scatterers.
