Abstract:
A method to achieve 2-D polarization-encoding in the light field and polarization-selection based on liquidcrystal spatial light modulator( LCSLM) is proposed. The basic idea is to change the polarization state of output light wave with the gray-level working on LCSLM. The capability of changing the polarization distribution of a light field based on LCSLM is studied in this paper.We encode the polarization state of incident beam with different gray levels working on LCSLM’s different areas, so different output informations with different polarization states could be obtained. The experimental results show that the method can generate a light filed obtained two orthogonal polarization directions based on gray-level encoding, and the polarization-selective diffraction system can realize polarization-selection of the diffractive field.
