Abstract
A system for analyzing fluid includes a housing having first and second opposing surfaces spaced to form a fluid chamber, a light source disposed to direct light at the first surface of the housing; and a digital imaging circuit disposed to detect light at the second surface of the housing. The digital imaging circuit includes a pixel array configured to capture one or more digital images of an illuminated fluid. The system also includes a processor configured to: capture multiple digital images of the fluid at different camera exposure levels, calculate a net radiant energy value at a plurality of different integration times within at least two images, calculate a slope of the net radiant energy value with respect to integration time in a selected image, and determine size distribution and volume fraction of particles within the fluid based on the calculated slope.
