FIELD: fire safety.
SUBSTANCE: optical fire detectors and sensors used to examine a confined space for the appearance of smoke in it, as well as the appearance or change of thermal convection flow. The device contains an optical part, which includes a source of optical radiation, an analyzed space and a series-connected optical splitter and a condenser, a photoreceiving part, including the first and second photoreceiving units, the device also contains a signal processing unit, an information output unit.
EFFECT: possibility of remote monitoring, as well as an increase in spatial resolution.
