Abstract
An imaging system with an imaging mechanism which includes polarization analyzers, which may be crossed polarization analyzers, positioned to provide birefringence images of particles in the fluid passing through the flow chamber. Captured images are of high resolution and may be used in comparison to known images of a library of images. The system and related method enhance the accuracy and sensitivity of particle monitoring by utilizing birefringence imaging combined with particle analysis and the detection of each particle's characteristic features, such as crystalline features. The system includes a scatter detector used to trigger backlighting of the flow chamber and capture images of particles therein.
