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.

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.

A compound-eye imaging device comprises an imaging device body having 9 optical lenses and a solid-state imaging element for imaging unit images formed by the optical lenses. Assuming that the combination of each of the optical lenses with a corresponding divided area of the solid-state imaging element to image each of the corresponding unit images is an imaging unit, thereby forming multiple imaging units, the respective imaging units have randomly different optical imaging conditions. For example, the focal lengths of the 9 optical lenses are set to have random values in which the optical lenses are arranged to have random distances between adjacent ones thereof in a direction parallel to the major surface of the solid-state imaging element. This compound-eye imaging device substantially prevents unit images formed by respective imaging units from being the same, making it possible to easily increase the definition of a reconstructed image.

Compound-eye imaging device

An imaginary object plane is set in front of an imaging device body (plane setting step). A part of optical conditions of optical lenses are changed as variables, and positions of points (pixel observation points) on the imaginary object plane where lights coming from pixels of a solid-state imaging element and back-projected through the optical lenses are calculated (pixel observation point calculating step). The dispersion in position of the calculated pixel observation points is evaluated (evaluating step). Finally, a set of values of the variables giving maximum evaluated dispersion of the calculated pixel observation points is determined as optimum optical condition of the optical lenses (condition determining step). This reduces the number of pixels which image the same portions of the target object, making it possible to reduce portions of the same image information in multiple unit images, and to stably obtain a reconstructed image having a high definition.
