Abstract

Arbitrary polarized beams, including homogeneously polarized beams and cylindrical vector beams, have been generated by an experimental setup with one phase-only liquid crystal spatial light modulator, and a four-path method was demonstrated to measure the polarization degree of detected beams. Besides, another method was proposed to measure the polarization directions of cylindrical vector beams. The polarized states can be calculated by controlling the spatial light modulator and optical intensity obtained from a CCD. The generation setup and detection methods have simple structure and low cost, and they are available for multi wavelength input beams, and the detection methods can realize real-time and on-line measurement.
