Abstract: There is provided a gas sensing device for sensing a certain gas that is associated with a certain spectral band, the gas sensing device may include a passive gas sensor that is configured to generate passive gas sensor detection signals that are responsive to the certain spectral band; a passive dummy sensor that is configured to generate passive dummy sensor detection signals that are indifferent to the certain spectral band; and at least one circuit that is configured to detect a presence or absence of the certain gas within a certain volume that is located within the fields of view of the passive gas sensor and the passive dummy sensor based on a comparison between the passive gas sensor detection signals and the passive dummy sensor detection signals.

Abstract: A device that may include a narrowband filter that is arranged to pass radiation within a main signal waveband in which a muffle 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 muffle flash.
