Title:
ELECTROMAGNETIC WAVE PHASE/AMPLITUDE GENERATION DEVICE, ELECTROMAGNETIC WAVE PHASE/AMPLITUDE GENERATION METHOD, AND ELECTROMAGNETIC WAVE PHASE/AMPLITUDE GENERATION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2018/034241
Kind Code:
A1
Abstract:
This electromagnetic wave phase/amplitude generation device is provided with: a radiation unit for irradiating an imaging subject with electromagnetic waves of a random irradiation pattern over a spatial frequency of a determined state of the electromagnetic waves being radiated for respective subdivided regions; an imaging unit for generating a captured image by imaging scattered electromagnetic waves, which are electromagnetic waves obtained when the imaging subject scatters the electromagnetic waves of the irradiation pattern radiated from the radiation unit; and a generation unit for generating information indicative of at least the phase and amplitude of the electromagnetic waves coming from the imaging subject by performing a sparse constraint operation based on the sparsity of the imaging subject on the basis of the captured image generated by the imaging unit, information indicative of the irradiation pattern, and information indicative of a signal of the imaging subject.
