摘      要：It is known that one can determine the mode orders （i.e., the azimuthal order and radial order） of a partially coherent LGpl beam （i.e., a partially coherent vortex beam） based on the measurement of the cross-correlation function （CCF） and the double correlation function （DCF） together. The technique for measuring the CCF is known. In this Letter, we propose a method for measuring the DCF. Based on the proposed method, the deter- mination of the mode orders of a partially coherent LGpll beam is demonstrated experimentally.
