The disclosure is directed to organic particle sorting and identification. High frequency pulses of circularly polarized light, alternating between left and right, is formed by passing the beam (12) from a laser (10) through, in succession, a beam expander (14), a polarizer (16), an optical modulator (18) driven by an oscillator (20) and focussing and shaping optics (22) to intersect a fast moving stream of organic particles (24). Circular intensity differential scattering and linear intensity differential scattering are monitored by collecting light scattered from stream (24) with, in succession, collection optics (28), optical modulator (30) driven by oscillator (31), polarizer (32), spatial filter (34), and photodetector (36). |
