Abstract

Several proposals are known for the simultaneous measurement of particle velocities and size. In this study we propose to measure the ratio of the contents of two specific channels of the Fourier transform of the autocorrelation function of the predetection signal corresponding to single particle transit of the sensing volume. We show that in a wide range of experimental conditions this ratio is a monotonous function of particle size. This circumstance leads to the possibility of defining calibration curves for practical devices.
