Abstract
FIELD: measurement technology, emergency alarm systems. SUBSTANCE: device includes source of coherent radiation, multimode light guide and photodetector connected to register. Device is supplemented with fiber-optical coupler and reflector. Output of source of coherent radiation is connected to first port of fiber-optical coupler, which second port is connected to lead-out of multimode light guide which second lead is connected to mirror of reflector and which third port is connected to input of photodetector. EFFECT: increased sensitivity and probability of detection. 2 dwg
