New Method of Generating Vectorial Polarized Beams
In order to resolve the complicated structure and higher cost problems with current vectorial polarized beams (VPB) generating devices, a new method of generating vectorial polarized beams is proposed by using a ring device with many linear polarizer components concentric circles which is called polarization axis finder (PAF). Based on the special structure property of PAF, nature light emitted by a light emitting diode (LED) encounters the PAF, and then the azimuthally polarized beam (APB) is formed. A polarization transformation of APB to radially polarized beam (RPB) is consisted of two half-wave plates with angle of 45° between the two fast axes. The intensity distributions with different polarizer directions for vectorial polarized beams are observed. The experimental results generally agree with the results previously reported, which can verify the validity and practicality of this method.
