Abstract:
    This invention discloses one thin particle measurement method based on laser feedback effect, which uses laser added spectrum resonance chamber thin particle diffraction to generate laser feedback effect, wherein, through measuring light energy changes of laser it measures particle size, speed and number parameters; the measurement device adopts heliium neon laser added with concaved total reflection lens and focus co-focus design added resonance chamber relative to difference sizes and speed.
