Renner, Otto, Boisselle & Sklar, LLP
Imaging device having array of spectroscopic sections wherein an interval between two spectroscopic sections at a periphery of an imaging plane is smaller than an interval between two spectroscopic sections at a center of the imaging plane
The imaging device disclosed herein includes: a plurality of photodetection sections having a light-receiving face, the plurality of photodetection sections being disposed in a two-dimensional array 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; and a plurality of spectroscopic sections having a greater refractive index than the transparent layer and being disposed in a two-dimensional array in a plane of arrangement. 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. An interval between two adjacent spectroscopic sections along a predetermined direction is smaller at the periphery than at the center of the imaging plane.
