    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 particle detector (10) including a chamber (12), a first aspirator (14), a sensor(s) (28), a controller (20) and clean air supply (18). The controller, when in a detecting mode, receives an indicative signal from the sensor and applies logic to the indicative signal to generate a further signal (22), and when in the purge mode controls substantial purging of the chamber of sample fluid with clean fluid from the clean fluid supply. The controller receives the indicative signal when the chamber is so purged and if necessary adjusts the logic in response thereto.

    Abstract: A smoke detector (10) is disclosed which uses a beam of radiation such as a laser (16), to monitor a region, such a room (12). A camera (14) is used to capture images of part of the room (12), including a path of the laser beam. Particles in the laser beam scatter light (30), and this is captured by the camera (14) for analysis. A processor (20) extracts data relating to the scattered light (30) to determine the density of particles in the beam, to determine the level of smoke in the region. The laser may have a modulated output (38) so that images captured without the laser can be used as a reference point and compared to images taken with the laser on, to assist in determining the level of scattered light (30) compared to ambient light. Filters (24, 26) may be used to decrease signals generated from background light.

    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.
