Solid State Imaging Element And Imaging System

Abstract: This technology relates to a solid state imaging element and an imaging system that can provide a solid state imaging element and an imaging system in which achievement of a visible/near infrared spectroscopic/imaging device that has high sensitivity and high wavelength resolution is possible and with which two dimensional spectral mapping with high spatial resolution is made possible. The solid state imaging element has a two dimensional pixel array and a plurality of types of filters disposed so as to face the image element region of the two dimensional pixel array are provided with a spectroscopic function and have a periodic microscopic pattern shorter than the wavelength to be detected. Each filter is larger than a photoelectric conversion element for each pixel in the two dimensional pixel array and forms a single unit in which one type of filter is disposed for a plurality of photoelectric conversion element groups that are adjacent. A plurality of types of filters are disposed for adjacent unit groups and form a filter bank and N × M units (where N and M are integers of 1 or more) are disposed such that the filter bank faces the pixel region of the two dimensional pixel array.
