Photon counting based particles detection method and apparatus
CCDC CBC
A method for detecting biological aerosols using a photon counting technique to determine the presence of particles is described. A Schmitt trigger is used to prevent over counting of particle events and for greater stability and noise immunity. An alarm determination is made using time-based statistical data derived from the observed fluorescent and scattered photon data.
