Abstract (en)
[origin: EP3413280A1] A system for detection and monitoring includes one or more light sources configured to emit light into a monitored space. At least one of the light sources is configured to emit a respective emission cone having a respective emission cone axis. One or more light sensing devices are configured to receive scattered light. At least one of the one or more light sensing devices defines a respective acceptance cone having a respective acceptance cone axis. The emission cone axis of the emission cone, and/or the acceptance cone axis of the light sensing device is angled toward the other. A processor is operatively connected to the at least one light sensing devices to evaluate the scattered light for the presence of particulates in the monitored space.
