Claim 13:
14. An imaging detector, comprising:
a plurality of pixels, each pixel comprising:
a detection material that generates a measurable parameter in response to X-ray photons; and
a plurality of sub-pixel resolution readout structures, wherein the sub-pixel resolution readout structures are in an alternating pattern with a spacing therebetween that is larger than a frequency of a phase-contrast interference pattern but small enough to enable charge sharing between adjacent sub-pixel resolution readout structures when an X-ray photon hits between the adjacent sub-pixel resolution readout structures;

readout circuitry configured to read out signals from the plurality of sub-pixel readout structures;
wherein the plurality of sub-pixel resolution readout structures comprises two or more electrodes having alternating arms that form an interleaved comb structure; and
wherein each electrode of the two or more electrodes is shaped so that adjacent electrodes form an interlocked triangular pattern between themselves to enable charge sharing, and wherein the adjacent electrodes overlap in a direction parallel to a path of the X-ray photons, and wherein each electrode of the two or more electrodes comprises a first segment physically separate from a second segment in a co-linear arrangement along the direction, the second segment being configured to enable accurate measurement of the X-ray photons in the presence of an X-ray photon flux that saturates the first segment.
