Abstract: A flash detection device comprises at least a first and a second sensor module, wherein each of the sensor modules comprises at least a photodiode for detecting an irradiance emitted by a source, and the first sensor module comprises at least an angular efficiency attenuator configured for attenuating the irradiance received by the photodiode according to a predetermined angular efficiency profile, wherein the at least first and second sensor modules are configured for collecting light from substantially the same field of view, and the angular efficiency attenuator of the first sensor module causes the first and second sensor modules to have complementary predetermined angular efficiency profiles, so that, for angles of view within a common field of view of the first and second sensor modules, a combination of irradiance measurements of the first and second sensor modules enables to derive an irradiance source angle of the source.

Abstract: The present disclosure provides a method including memorizing a sequence of high-resolution images of a scene in a buffer, obtaining radiation emission readings from one or more photo detectors, detecting a suspected flash event based on processing the radiation emission readings from the one or more photo detectors. The method may further include that the detecting occurs at a first instant, retrieving from the buffer high-resolution images of the scene including at least one image that was captured prior to said first instant, and processing the high-resolution images of the scene to determine a geolocation of the suspected flash event.
