    Abstract: The system includes an excitation source for providing a beam of electromagnetic radiation having a source wavelength. A first wavelength selective device is positioned to be impinged by the beam of electromagnetic radiation. The first wavelength selective device is constructed to transmit at least a portion of any radiation having the source wavelength and to reflect radiation of other wavelengths. A medium containing particles is positioned to be impinged by the beam of electromagnetic radiation. At least a portion of the beam of electromagnetic radiation becomes scattered within the medium, the scattered electromagnetic radiation including forward scattered electromagnetic radiation and backward scattered electromagnetic radiation. An optical detector is positioned to receive backward and/or forward scattered electromagnetic radiation.

    Abstract: A particle detector has a sample area of cross section no in excess of about 2 mm for containing environmental fluid, a light source on one side of the sample area for directing a collimated or nearly collimated beam of light through the sample air or water so that part of the light beam will be scattered by any particles present in the air or water while the remainder remains unscattered, and a beam diverting device on the possible side of the sample area for diverting or blocking at least the unscattered portion of the beam of light and directing at least part of the scattered light onto a detector. The detector produces output pulses in which each pulse has a height proportional to particle size and a pulse height discriminator obtains the size distribution of airborne particles detected in the air or water sample at a given time from the detector output. The detector may also include a device for discriminating between biological agents and inorganic particles.

    Abstract: A particle detector has a sample area of cross section no in excess of about 2 3 mm for containing environmental fluid, a light source on one side of the sample area for directing a collimated or nearly collimated beam of light through the sample air or water so that part of the light beam will be scattered by any particles present in the air or water while the remainder remains unscattered, and a beam diverting device on the opposite side of the sample area for diverting or blocking at least the unscattered portion of the beam of light and directing at least part of the scattered light onto a detector. The detector produces output pulses in which each pulse has a height proportional to particle size and a pulse height discriminator obtains the size distribution of airborne particles detected in the air or water sample at a given time from the detector output. The detector may also include a, device for discriminating between biological agents and inorganic particles.
