%X The article presents a method to measure atmospheric suspended particles with a double facula which consists of a group of lens and a diode laser. Laser was scattered when particles go through the double facula. APD(avalanche photoelectricity diode) detects the scattered light and outputs a double-peak signal. Particle size, sum of particles and lognormal size spectrum can be determined by time of flight. Experimental results show that the particle spectrum in the air is of normal Gaussian distribution, in agreement with the theoretical analysis.
