Abstract:
1. A system for imaging particles in a fluid, the system comprising: a. A rectangular flow chamber having a width dimension and a depth dimension, the flow chamber including a channel arranged to transport the fluid therethrough at a selectable rate, wherein the flow chamber is a low fluorescence structure with an index of refraction of about 1.5 and having a ratio of the width dimension to the depth dimension that is greater than 10:1; b. a device configured to create a controllable fluid flow rate in the flow chamber; c. a backlighting generator arranged to illuminate the fluid in the flow chamber; d. an objective arranged to receive incident optical radiation from the flow chamber; e. a light source arranged to generate light scatter and/or fluorescence from particles; f. one or more detectors to detect light scatter and/or fluorescence emitted from the particles upon illumination; g. a signal processor configured to receive signals from the one or more detectors; and h. an image capturing system including means to capture images of particles in the fluid.
