Many advanced fields in optics now require the conversion of any spin angular momentum to orbital angular momentum. J-plate is an optical retarder element using metasurface that can achieve arbitrary spin-to-orbital angular momentum conversion of light. In this paper, two liquid crystal spatial light modulators are employed to simulate the conversion process of the arbitrary programmable J-plate. Experiments have tested the OAM outputs corresponding to different input polarization states. The results are consistent well with expectations.
