Claim Text:
1. An imaging device comprising: a plurality of photodetection sections having a light-receiving face, the plurality of photodetection sections being disposed in a uniform two-dimensional array of photodetection sections along a first direction and along a second direction different from the first direction, such that the light-receiving faces of the plurality of photodetection sections constitute an imaging plane; a transparent layer having an incident face and an outgoing face and being disposed so that the outgoing face opposes the imaging plane; and a plurality of spectroscopic sections having a greater refractive index than a refractive index of the transparent layer and being disposed in a two-dimensional array of spectroscopic sections in a plane of arrangement, the plane of arrangement being within the transparent layer and parallel to the imaging plane, wherein, zeroth order diffracted light and ±first order diffracted light, derived from light transmitted through each spectroscopic section and a portion of the transparent layer neighboring the spectroscopic section, respectively enter distinct photodetection sections among the plurality of photodetection sections; and an interval between two adjacent spectroscopic sections in the two-dimensional array of spectroscopic sections along a predetermined direction is smaller at a periphery than at a center of the imaging plane.
