Particle detector, system and method

摘要

The invention provides use of one or more emitted beams of radiation (16), for example, laser beam(s), in combination with an image capturing means (14), for example, one or more video cameras and/or optical elements to detect particles (30), for example, smoke particles, located in an open space (12).

主权项

1. A method performed by a particle detection system, said method being configured to synchronise between a light source of the particle detection system and an image capturing means of the particle detection system, the method comprising:
allowing the light source to oscillate on and off at a predetermined rate; identifying the light source in video images captured by the image capturing means and; continually modifying the image capturing means frame rate to remain in synchronisation with the oscillation of the light source.
