Document Type and Number:
WIPO Patent Application WO/2017/133045
Kind Code:
A1
Abstract:
A biological and non-biological aerosol real time monitor, comprising a laser light source assembly (100) for emitting a laser beam and forming a line-shaped laser spot at a particle excitation position of air flow to be tested; an enclosed photoelectric measurement room (8), wherein the laser light source assembly (100) is provided at a laser entrance port at the rear end of the enclosed photoelectric measurement room (8); inside the enclosed photoelectric measurement room (8), the air flow to be tested and the optical axis of the laser beam, emitted by the laser light source assembly (100), in a traveling direction intersect at the particle excitation position where the line-shaped laser spot is; a scattered light signal reflecting mirror (21) and a fluorescence signal reflecting mirror (22) bilaterally and symmetrically provided to center a measurement point formed by intersection of the laser beam emitted by the laser light source assembly (100) and the air flow to be tested; a scattered light signal detector (17) and a fluorescence signal detector (18) used to detect a scattered light signal and a fluorescence signal passing through openings of the reflecting mirrors. The portable monitor is capable of online monitoring.
