Abstract
An optical detection system for flow cytometry that uses two or more light sources positioned laterally at different distances from the central axis of the flow stream for providing light through different parts of the flow stream. By using two or more light sources, the particle position can be detected, and the alignment and width of the core stream can be monitored and controlled. In addition, the velocity and size of the particles can be more accurately determined than when only a single light source is used.
