Abstract
A particle classification system may include a volume to contain a fluid having a suspended particle, electrodes proximate the volume to apply an electric field to rotate the suspended particle, a focused light source, a scattered light sensor to sense light from the focused light source that has scattered upon impinging the rotating suspended particle and a controller to classify the particle based at least in part upon signals from the scattered light sensor.
Claims15
A particle classification system comprising:
- a volume to contain a fluid having a suspended particle;
- electrodes proximate the volume to apply an electric field to rotate the suspended particle;
- a focused light source;
- a scattered light sensor to sense light from the focused light source that has scattered upon impinging the rotating suspended particle;
- and
- a classifier to classify the particle based at least in part upon signals from the scattered light sensor.
A particle classifying method comprising:
- applying an electric field to induce rotation of a particle suspended within a fluid;
- sensing scattered light that has scattered upon impinging the particle during the rotation;
- and
- classifying the particle based upon the scattered light.
A non-transitory computer-readable medium containing instructions to direct a processor to:
- output control signals to an alternating current power source to apply an electric field to a particle suspended in a fluid;
- receiving signals from a scattered light sensor indicating rotation of the particle in response to the applied non-rotating electric field;
- and
- classify the particle based upon the indicated rotation of the
