Abstract
A system for identifying flash events including an optical imaging module with one or more optical imaging array, the optical imaging module configured for monitoring a region of interest to identify a tentative flash event. The system further includes a ranging module associated with the optical imaging module and configured to derive an estimated range to a location of the tentative flash event, and an acoustic verification module associated with the ranging module and with one or more acoustic sensor. The acoustic verification module is configured to determine whether an acoustic event corresponding to the tentative flash event is detected within a time window derived from the estimated range, thereby classifying the tentative flash event as either a verified flash event or a rejected flash event.
