A kind of plume divergence angle assessment method in Hall thrusters is proposed based on image processing. The detail assessment method and probable error is described and discussed. Comparing with the probe measurement method, this assessment method has advantages of being fast, simple and properly accurate. These advantages show that it is a competitive method to analyze dynamic characteristics of plume divergences in a low frequency oscillation time scale.
