<p>A semiconductor based X-Y addressable imager having an imaging array with a plurality of the pixels within the X-Y addressable imager, a photodetector within each of the plurality of pixels configured to sense a first bandwidth of light, a sense node within each of the pixels configured to sense a second bandwidth of light, a reset mechanism operatively configured to the photodetector and the sense node to allow resetting each of the photodetector and the sense node to a predetermined potential, the sense node being formed such that it does not have a light shield allowing the sense node to act as a second photodetector, and a transfer mechanism within each of plurality of pixels configured to transfer charge from the photodetector to the sense node. The X-Y addressable sensor in this embodiment can have either the first and second bandwidths being different, or the first and second bandwidths are the same. Another embodiment envisions the X-Y addressable imager is formed such that the bandwidth detected by the sense node and the photodetector is the same allowing for increased dynamic range of the photodetector. <IMAGE></p> |
