Laser warning and pointed optics detection using an event camera
conference paper
The detection of a threat before launch offers the best options to avoid the threat. However, detecting a threat before it concretizes remains a difficult task because of the obvious risk of error. The detection of a laser emission or of optics that are pointed towards the platform gives a significant cue of a hostile behaviour. In our work, we investigate if and how event (also called neuromorphic) cameras can be used to detect laser emission and combined with a laser source to detect retro-reflections caused by pointed optics. We explore how the high temporal resolution of the event stream can be used to extract temporal information on the laser signal. The approach is demonstrated for a laser warning receiver usecase and a retro-reflection detection configuration using data that was collected during the DeBeLa trial in Germany and that reproduce operationally relevant scenarios.
