SYSTEM AND METHODS FOR USE IN DETECTING HARMFUL AEROSOL PARTICLES |
摘要 |
A multi-spectral aerosol particle measurement system (100) including a long wavelength (e g, UV light, 340 nm) emitter (102) and a short wavelength (e g, UV light, 280 nm) emitter (108), an emitter reflector (114) such as a dichroic filter, that is transparent to long wavelength radiation (104) and reflective to short wavelength radiation (110), a flowing fluid (116) that contains particles (118) that may intersect first direction (106) such that they are sequentially exposed, producing elastic and inelastic emission wavelengths, including fluorescence, a collimating lens (122), and a detector reflector (124) to reflect short wavelength radiation and pass fluorescent radiation through one of a plurality of filters (126a-d) placed in the optical path of a detector (128) The detector reflector (124) reflects light having a wavelength shorter than 300 nm, so elastic scatter is detected by the light scatter detector (190). |
