| Abstract: | The APV (Adaptive Phase/Doppler Velocimetry) can be used to recognize particle material and measure particle size and velocity adaptively according to the Doppler frequency shift and the Doppler phase shift theory. Based on the light scattering theory of inconductive spherical particles, the hardware lay out of the APV system is studied, and the volume flux measurement of the water mist field is also discussed. The validity of the measurement is proved with the experiments. |
