Abstract
A system for classifying moving materials in real time, the system including a laser pulse generator operative to generate at least first and second laser pulses which impinge on the same impingement location on the moving materials, the first and second laser pulses being separated in time by up to 10 microseconds; and an absorption detector operative to sense an absorption spectrum at the impingement location over a detection time duration of up to 20 nanoseconds following the second laser pulse.
