Abstract
A system for calculating the volume of a plurality of particles is disclosed. The system includes three optical assemblies, each with a light source directing a beam of light of a wavelength along an optical axis at a specimen chamber, a filter positioned along the optical path after the chamber, and a sensor positioned along the optical path after the filter. The wavelength of each beam of light is different from the other wavelengths, and each optical axis is orthogonal to the other optical axes. A processor is connected to the sensors in each of the optical assemblies, and the processors perform the following steps: (a) capture an image from each of the three sensors; (b) based on the images, calibrate each sensor; (c) after calibration, capture an image from each of the three sensors; and (d) determine a volume of the plurality of particles, based on the images captured in step (c).
