Abstract
A particle detection system (), such as an active video smoke detection system, includes at least one illumination means () for directing a beam () of radiation through at least part of the air volume being monitored (), an image sensor () is positioned to capture images of at least part of a beam () from illumination means (); and means to analyse () the captured images to detect the presence of particles within the volume. At least 29 different aspects are described for improving the sensitivity, usability, and robustness of particle detection. These include, for example, configuring illumination means () to create a curtain of light or a rapidly-scanned beam across the air volume (), and configuring a reflector to steer or change direction of a beam reflected from illumination means ().
