ABSTRACT:
For the detection of heat sources within an area to be maintained under surveillance, several scanning units at different scanning stations are linked to a common radiation sensor by respective optical fibre transmission elements. A gating means, such as a rotary mask with an opening, is indexed stepwise to gate each transmission element in turn to the common sensor.
