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.
