    Abstract: Two or more soundproof cells arranged in a two-dimensional manner are provided. At least one of the soundproof cells is a first soundproof cell configured to include a first frame having a first through-hole. At least one of the other soundproof cells is a second soundproof cell including a second frame having a second through-hole and a film fixed to the second frame. A first shielding peak frequency, which is determined by the first through-hole of the first soundproof cell and at which a transmission loss is maximized, is present on a lower frequency side than a first natural vibration frequency of the film of the second soundproof cell, and sound in a predetermined frequency band centered on the first shielding peak frequency is selectively insulated.

    Abstract: Pixels of a mask image with which a target object is irradiated are shifted by a determined distance by sequentially turning on one light emission point or two or more light emission points of a light source with respect to a single mask pattern generated in a spatial modulation element, a pixel shift amount of the mask pattern determined by a position of the light emission point to be turned on of the light source is known, the target object is irradiated with mask images according to a plurality of mask patterns depending on the positions of the light emission point of the light source and the spatial modulation element, and a computer calculates a correlation between a light intensity detected by a detector and the mask image with which the target object is irradiated, to construct an image of the target object. With this, an imaging device and an imaging method capable of achieving an increase in speed of mask pattern irradiation in single-pixel imaging and significantly increasing an input speed of single-pixel imaging are provided.
