摘要: A method for fluorescence probing of particles flowing in a fluid includes defining trigger volume the by intersecting plurality substantially orthogonally aimed laser beams, each different wavelength, detecting light scattered from vicinity particle detectors sensitive to wavelength corresponding beam, with pulsed triggered detectors, collecting emitted detection and focusing it region, focused region. The invention also devices carrying out foregoing method.
