Abstract: Provided are a hyperspectral image sensor and a hyperspectral imaging system including the hyperspectral image sensor. The hyperspectral image sensor includes a light-receiving sensor that is pixelated, and a plurality of metasurfaces that are arranged in front of the light-receiving sensor apart from each other in a stacking direction, and each have an array of meta-atoms. At least one of the plurality of metasurfaces is a random metasurface in which the meta-atoms are disorderly arranged, and a speckle pattern is formed on a sensing surface of the light-receiving sensor by the plurality of metasurfaces.
