Since the optical alignment of optically functional liquid crystal materialcan control the spatial distribution of optical anisotropy with high degree of freedom, it is applied to the fabrication of various optically anisotropic device.In this study, we simulated the wavefront / polarization conversion characteristics of optically anisotropic device fabricated by vector hologram recording by using two vector vortex beams with equal distribution of polarization in beam cross sectionto LC and different values of topological charge.
