摘要

Strong experimental data supporting the theoretical relation-ship between linear and circular depolarizations for randomly oriented particles are presented. The analysis of the data leads to the first ex-perimental validation of the theoretical representation of the scattering Mueller matrix as having indeed only one free parameter for randomly ori-ented particles, which is the depolarization parameter, d. Consequently, there is no added information on the nature of the aerosols when the four Stokes parameters are measured for randomly oriented aerosols, as opposed to measuring only the linear polarization or only the circular polarization related parameters. This conclusion has a direct impact on the analysis of the level of complexity of the systems that are required to analyze aerosols based on their depolarization signatures.
