摘要

A spatially variable retardation device,an SQWP,is designed to generate polarization vortex beams.The transformation of Laguerre-Gaussian beams by the SQWP is further studied,and it is found that the SQWPs can also be used to generate helical beams and measure the topological charges of helical beams.
