1. An apparatus for electromagnetic irradiation imaging, comprising:
one or more pixels, each pixel comprising a plurality of detector cells arranged in a row extending in a row direction, wherein the plurality of detector cells comprise charge-coupled device (CCD) sensors that are configured to generate a signal proportional to detected energy of the photons;
wherein the row is configured to receive photons at an incident surface at one end of the row, the received photons penetrating the plurality of detector cells in the row direction; and
wherein the plurality of detector cells of the same row are configured to generate respective signals that collectively indicate an energy-resolved spectral profile of the photons based on the penetration of the photons into the row of detector cells.
