Abstract: A 3D stacked electro-optical radiation imaging device with a plurality of integrated circuit layers, the device having a pixelated array of semiconductor detector elements, in which each detecting element is electrically connected a stacked integrated circuit. The stacked integrated circuit has a mixed signal layer and a reconfigurable layer. The mixed signal layer has a passive signal path and an active signal path. A readout decoder block controls operation of the passive paths. The active signal path triggers readout upon transient event detection and is readout by an address arbitration control block, the address arbitration control block operating independent and asynchronous to the readout of the passive path and transient event detection initiates the identification of the location of and readout of the signaling active path. The reconfigurable layer has processing units that each correspond to one or more pixels in the pixelated array. The processing units are reconfigurable through received signals from either the passive path, the active path, or an external signal. A controller programs and communicates with the mixed signal layer and reconfigurable layer

Abstract: An imaging device in accordance with the present disclosure comprises of a pixelated array of semiconductor detector elements, each of the pixels in the array having an in-pixel integrated circuit, the integrated circuit having a comparator, a readout decoder block, and an address arbitration control block. The readout decoder block reads out the integrated signals of the pixels. The address arbitration control block determines the pixel address of the pixels charging beyond a threshold voltage, the threshold exceedance determined by the comparator. The addressed pixels are provided a timestamp for each of the pixels integrating beyond the threshold voltage, the timestamp provided by an off-pixel time-to-digital converter (TDC), the value of the timestamp corresponding with the accumulated charge of the pixel.

Abstract: An imaging device comprises of a pixelated array of semiconductor detector elements, in which each detecting element is electrically connected to an integrated circuit, the integrated circuit of each of the pixels comprising a passive signal path and a transient signal path. The passive path provides consecutive frame or scene imaging and the transient path detects the transient electromagnetic events such as laser pulses. The transient path is electrically connected to a timing circuit, the timing circuit for determining the time-of-flight of return pulses emitted from the electromagnetic source detected by the transient signal paths. Wherein the passive path and transient path operate simultaneously enabling simultaneous passive and LADAR imaging.
