Abstract: An electromagnetic wave detecting device comprising: an emission unit configured to emit electromagnetic waves having coherence; an electromagnetic wave modulating unit configured to modulate one or both of a phase and an amplitude of the emitted electromagnetic waves and to change a state of the modulation relative to an imaging target; and a post-modulation electromagnetic wave intensity detecting unit configured to detect an intensity of post-modulation electromagnetic waves, which are the modulated electromagnetic waves acquired by modulating the electromagnetic waves emitted from the emission unit using the imaging target and the electromagnetic wave modulating unit, using one pixel.

Abstract: An electromagnetic wave phase/amplitude generation device includes a radiation unit configured to radiate electromagnetic waves of a random radiation pattern on a spatial frequency in which a state of the electromagnetic waves to be radiated for each divided region is determined to an imaging object, an imaging unit configured to generate a captured image by imaging scattered electromagnetic waves that are electromagnetic waves generated when the imaging object scatters the electromagnetic waves of the radiation pattern radiated by the radiation unit, and a generation unit configured to generate information indicating at least a phase and amplitude of the electromagnetic waves from the imaging object by performing an arithmetic sparsity constraint operation according to sparsity of the imaging object on the basis of the captured image generated by the imaging unit, information indicating the radiation pattern, and information indicating a signal of the imaging object.
