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

摘要

The electromagnetic wave phase amplitude generation device comprises: an irradiation unit for irradiating an imaging object with electromagnetic waves having a random irradiation pattern on a spatial frequency where the state of the electromagnetic wave irradiated for each divided region is determined; and an irradiation pattern irradiated by the irradiation unit The imaging unit generates an imaged image by imaging a scattered electromagnetic wave which is an electromagnetic wave scattered by the imaging target, the imaged image generated by the imaging unit, information indicating an irradiation pattern, and a signal of the imaging target A generator configured to generate information indicating at least a phase and an amplitude of an electromagnetic wave from an imaging target by performing sparse constraint calculation based on the sparsity of the imaging target based on the information.
