Abstract: A particle detection system (100), such as an active video smoke detection system, includes at least one illumination means (102) for directing a beam (106) of radiation through at least part of the air volume being monitored (1 10), an image sensor (104) is positioned to capture images of at least part of a beam (106) from illumination means (102); and means to analyse (107) 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 (102) to create a curtain of light or a rapidly-scanned beam across the air volume (110), and configuring a reflector to steer or change direction of a beam reflected from illumination means (102).

Abstract: A method of particle detection in an aspirated particle detection system, the system having a sampling pipe network and a particle detector. The sampling pipe network includes at least one sampling pipe in fluid communication with the particle detector, a plurality of sampling inlets through which sample air can enter the at least one sampling pipe, and an opening in the at least one sampling pipe upstream of the plurality of sampling inlets, wherein the opening has lower flow impedance than any one of the sampling inlets. The method includes drawing sample air to the particle detector through the air sampling network; analysing the sample air with the particle detector; entering an amplification phase, in the event that a concentration of particles in the sample air greater than a predetermined threshold is detected, to create a plurality of sample air packets in the sampling pipe, wherein each sample air packet corresponds to a sampling inlet and includes an amplified concentration of air drawn from the corresponding sampling inlet; transporting the sample air including the plurality of sample air packets through the sampling pipe to the particle detector; and determining through which sampling inlet any particles entered the particle detection system.

Abstract: The invention provides a method of detecting particles. The method includes emitting a beam of radiation from a light source into a monitored region and detecting an increase in scattered radiation intensity in images of the region captured by a camera, the increase in scattered radiation intensity in images of the region indicating the presence of the particles wherein the beam of radiation and a means of detecting the increase in scattered radiation intensity in images are adapted to communicate data. The field of view of the camera includes at least part of a path of a laser beam and the laser beam does not impact on the camera directly. The light source is within the field of view of the camera.
