Systems and methods for reconstruction of digital holograms

A system for reconstructing a digital hologram comprising:

• a digital holographic image acquisition subsystem operative for acquiring a digital hologram of a surface having at least one three-dimensional feature thereon;
• a wavefront reconstructor operative to reconstruct a wavefront based on said digital hologram;
• a phase map generator operative to receive said wavefront and to generate a phase map of at least a portion of said surface based on said wavefront, said phase map including phase ambiguities;
• an image processing subsystem operative to obtain at least one additional image of said surface, wherein said image processing subsystem comprises an AI network operative to generate a series of incoherent light images corresponding to a series of digital wavefronts of said surface, said series of digital wavefronts being obtained by said image processing subsystem digitally propagating said wavefront through a series of depths within said surface and obtaining said series of digital wavefronts corresponding to said series of depths;
• an image analyzer operative to obtain height data relating to said three-dimensional feature from said at least one additional image of said surface, said height data being obtained with a first precision;
• a phase ambiguity resolver operative to resolve said phase ambiguities in said phase map based on said height data;
• and
• a height calculator operative to derive a height of said at least one three-dimensional feature based on said phase map following said resolving of said phase ambiguities therein, said height of said three-dimensional feature being derived with a second precision more precise than said first precision.
