The vector optical field with complex spatial structure plays an important role in the manipulation of the optical fields. As one of the eigen laser fields in the elliptic coordinate system, Ince-Gaussian (IG) field has richer spatial degrees of freedom than Laguerre-Gaussian beam and Hermite-Gaussian beam, and it is one of the fundamental fields to construct a complex vector optical field. This work is based on the theory of spatial superposition of the orthogonal polarized even and odd IG modes. IG vector optical fields with different orders and spatial structures are generated by a spatial light modulator which modulate the even and odd modes separately. Experimental results are studied and compared with the simulated results. The results demonstrate the feasibility of generating IG vector optical fields by dual modulation and parallel measurement.
