Abstract:
1. A system for measuring properties of a particle contained in a flow of fluid, comprising: (a) a sampling volume into which the flow of fluid containing the particle can be directed, the sampling volume including a region of interest; (b) an acoustic transducer configured to direct acoustic energy toward the particle when the particle is proximate the region of interest, such that the particle experiences a vibrational effect due to the acoustic energy while in at least a portion of the region of interest; (c) a light source for illuminating the region of interest with light; (d) a sensor for capturing light scattered by the particle while the particle is in the region of interest, producing a signal; and (e) a processor coupled to the sensor, the processor manipulating the signal from the sensor to determine at least one property of the particle in the region of interest.
