Asynchronous readout array

摘要

An imaging device is disclosed, the device comprising a pixelated array of semiconductor elements, in which each detecting element is electrically connected to an integrated circuit, the integrated circuit comprising a passive signal path and an active signal path. The passive path provides consecutive frame imaging and the active path detects the location of transient events. The device further comprising a readout decoder block, the readout decoder block controlling operation of the passive paths. Additionally, the device comprises of an address arbitration control block, the address arbitration control block controlling operation of the active paths, wherein the address arbitration control block readout of the active paths are independent of readout of the integrated signal readout from the passive paths.

1. A dual mode electro-optical radiation imaging device, the device comprising:
a pixelated array of semiconductor detector elements, in which each detecting element is electrically connected to an integrated circuit, the integrated circuit comprising a passive signal path and an active signal path, wherein the active signal path triggers readout upon transient event detection; a readout decoder block, the readout decoder block controlling operation of the passive paths; and an address arbitration control block, the address arbitration control block controlling readout and operation of the active path, wherein the address arbitration control block operates independent and asynchronous to the readout of the passive path, and wherein transient event detection initiates the identification of the location of and readout of the signaling active path.
