Abstract
A particle imaging system may include a volume to contain a fluid having a suspended particle, electrodes proximate to the volume to apply an electric field to rotate the suspended particle, an optical sensor comprising a first region and a second region and a diffraction element to split an image of the suspended particle into a bright field image focused on the first region and a spectral image focused on the second region.

A particle imaging system comprising:
- a volume to contain a fluid having a suspended particle;
- electrodes proximate to the volume to apply an electric field to rotate the suspended particle;
- an optical sensor comprising a first region and a second region;
- and
- a diffraction element to split an image of the suspended particle into a brightfield image focused on the first region and a spectral image focused on the second region.
A particle imaging method comprising:
- applying an electric field to a particle suspended in a fluid to rotate the suspended particle;
- splitting an image of the rotating suspended particle into a brightfield image focused on a first region of an optical sensor and a spectral image focused on a second region of an optical sensor;
- and
- constructing a 3D image of the rotating suspended particle based upon a combination of the brightfield image and the spectral image as sensed by the optical sensor.
A non-transitory machine-readable medium containing instructions to be followed by a processor, the instructions comprising:
- particle rotation instructions to direct the processor to electrically charged electrodes to apply an electric field to rotate a particle suspended in a fluid;
- and
- imaging instructions to direct the processor to construct a 3D image of the particle, during rotation of the particle, from a combination of a brightfield image of the rotating suspended particle and a spectral image of the rotating suspended particle concurrently sensed.
