1. A method for rapidly calculating a three-dimensional polarimetric dimension, comprising steps of:
determining that an incident light field is a coherence matrix of a partially coherent Schell-model beam, and decomposing the coherence matrix into a form of multiplying an incident electric field by a coherence structure matrix of the incident light field;
obtaining an electric field near a focal field after the incident electric field passes through a tight focusing system according to the vector diffraction theory, and describing a second-order correlation characteristic of a partially coherent vector beam near a tightly focused field by using a coherence matrix to obtain a tightly focused coherence matrix;
obtaining a tightly focused polarization matrix based on the tightly focused coherence matrix; and
rotating the tightly focused polarization matrix into an intrinsic coordinate frame of the tightly focused polarization matrix, and calculating a three-dimensional polarimetric dimension of the partially coherent Schell-model beam in the tightly focused field.
