Abstract
A device that may include a narrowband filter that is arranged to pass radiation within a main signal waveband in which a muzzle flash is expected to include energy above a first energy threshold; a first single photon avalanche diode (SPAD) arranged to detect photons of the main signal waveband during different points in time and to output first digital detection signals representative of the photons of the main signal waveband; and a signal processor that is arranged to receive the first digital detection signals and to detect, in response to at least the first digital detection signals, the muzzle flash.
