Detection system for airborne particles

摘要

This invention relates to a detection system for particles suspended in a gas. The detection system includes an electrostatic precipitator constructed to collect the particles from the gas onto a collection surface using the force of an induced electrostatic charge on the particles. The detection system also includes an optical probe coupled with the electrostatic precipitator and constructed to probe the particles with a beam in order to detect the particles. The body of the electrostatic precipitator has a geometry that allows the beam to travel from the optical probe to the collection surface.
