Abstract：Some measuring results about droplets distribution of atomizing field in the desulfurisation tower are introduced and then present a popularly interesting question about measuringparticles moving trace at home and abroad in this paper. Questions are discussed as follows: Amethod of analyzing particles movernent with double exposure specklegram (DES), analyzing pin-ciple of DES, how to analyze particles movement by the hololens array, how to make DES of parti.cles movernent in two perpendicular planes and possibility of measuring particles' apace move tracewith optical parallel pocess and image analysis

Key words：particle; moving trace;measument method;optical parallel processing
