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.
