Abstract
Described herein is a particle detection system capable of spatially resolving the interaction of particles with a beam of electromagnetic radiation. Using a specific electromagnetic beam cross sectional shape and orientation, the detection sensitivity of a particle detection system can be improved. Also provided are methods for detecting and sizing particles in a manner that has low background signal and allows for spatially resolving the scattering or emission of electromagnetic radiation from particles.
