A light source is diffracted by the sample under investigation, and the diffracted complex-valued signal is split into L identical beams, each of which is directed towards a phase filter that modifies the phase of the incident signal at each spatial location. The phase-modified beams are then directed through a lens system, and their intensities are finally captured.
