In order to discuss the evolution of anomalous vortex beams with different polarization states from conical diffraction to birefringence, the influences of the propagation distance and propagation direction of the incident beam on the propagation characteristics are analyzed based on the conical diffraction theory. The conical diffraction characteristics of elliptical anomalou s vortex beams with different azimuth is also demonstrated. The results show the field intensity distribution of the circularly polarized anomalous vortex beam is more sensitive to the inclination factor than the circularly polarized Gaussian beam during t he evolution from conical diffraction to birefringence. The light intensity distribution properties of elliptically polarized light is between circularly polarized and linearly polarized light. W hen an elliptically polarized beam passes through a biaxial c rystal , the light field changes with the phase difference between the two perpendicular linearly polarized light of elliptically polarized light. It has application prospect in optical capture..
