Multi-sensor pixel architecture for use in a digital imaging system
A system and method for a multi-sensor pixel architecture for use in a digital imaging system is described. The system includes at least one semiconducting layer for absorbing radiation incident on opposites of the at least one semiconducting layer along with a set of electrodes on one side of the semiconducting layer for transmitting a signal associated with the radiation absorbed by the semiconducting layer.
1. A detector element for a digital imaging system, the detector element comprising:
at least one top electrode metal-semiconductor-metal (MSM) detector; and
at least one bottom electrode MSM detector;
wherein said at least one top electrode MSM detector and said at least one bottom electrode MSM detector share a common semiconducting layer.
2. The detector element of claim 1 wherein said top electrode MSM detector comprises:
the semiconducting layer; and
a top electrode MSM detector set of electrodes patterned on a top electrode side of the semiconducting layer.
3. The detector element of claim 2 wherein the top electrode MSM detector further comprises:
a blocking layer deposited between the semiconducting layer and the top electrode MSM detector set of electrodes.
4. The detector element of claim 3 wherein the top electrode MSM detector set of electrodes are spaced laterally apart.
5. The detector element of claim 2 wherein the bottom electrode MSM detector comprises:
the semiconducting layer; and
a bottom electrode MSM detector set of electrodes patterned on a bottom side of the semiconducting layer; the bottom side of the semiconducting layer opposite the top side of the semiconducting layer.
6. The detector element of claim 5 wherein the bottom electrode MSM detector further comprises:
a blocking layer deposited between the bottom electrode MSM detector set of electrodes and the semiconducting layer.
7. The detector element of claim 5 wherein the top electrode MSM detector set of electrodes and the bottom electrode MSM detector set of electrodes share common electrodes.
8. The detector element of claim 1 further comprising a set of scintillators adjacent to at least one of the top or bottom electrode MSM detectors.
9. The detector element of claim 8 wherein the scintillators within the set of scintillators are placed on a top and a bottom side of at least one of the top or bottom electrode MSM detectors.
10. The detector element of claim 9 further comprising a fiber optic faceplate located between two scintillators within the set of scintillators.
