Electromagnetic wave phase/amplitude generation device, electromagnetic wave phase/amplitude generation method, and electromagnetic wave phase/amplitude generation program

A method comprising:

• (a) directing radiated electromagnetic waves comprising a plurality of divided regions and having a random spatial distribution of amplitudes or phases toward an imaging object;
• (b) detecting scattered electromagnetic waves generated by the imaging object scattering the radiated electromagnetic waves;
• (c) forming an image of the imaging object from the scattered electromagnetic waves;
• (d) storing information associated with the radiated electromagnetic waves, the information associated with the radiated electromagnetic waves comprising distance-specific wavefront pattern information indicating states of wavefronts of the radiated electromagnetic waves at a plurality of distances;
• and
• (e) generation information indicating at least a phase and amplitude of a tomographic plane of the imaging object by performing an arithmetic sparsity constraint operation according to a sparsity of the imaging object based on the image and the information associated with the radiated electromagnetic waves.
