摘要： Measurement device for the detection and/or characterization of fluid-borne particles featuring a laser positioned for emitting pulses of laser light polarized in a first direction, in a measurement volume of a fluid flow path, each pulse having a pulse duration, and a means for directing the laser pulses polarized in a second different direction of polarization in the measurement volume. An optical spectrometer captures fluorescent light emitted by individual fluid-borne particles and measures the intensity of at least one wavelength at a sampling rate of at least three samples per pulse. The means for directing are configured to direct laser light polarized in the second direction each time a pulse of laser light crosses the measurement volume, the time delay between the two crossings being longer than the pulse duration and shorter than a travel time of the fluid in the measurement volume.

摘要： Measurement device and methods for the detection and/or analysis of fluid-borne particles. The measurement device comprises a means for producing a flow of fluid along a fluid flow path, a laser positioned for emitting a beam of laser light in a measurement volume of the fluid flow path; a lens set for collecting laser light scattered in the measurement volume by fluid-borne particles contained in the flow of fluid; a multipixel photo-detector positioned for detecting scattered laser light collected by the lens set. The lens set is configured for focusing the scattered light in a line being perpendicular to a flow direction (y) of the flow of fluid and at a focal distance of the lens set. The multipixel photodetector is positioned at a distance from the focal distance of the lens set and oriented with its longitudinal axis parallel to the line.
