Device and method for simultaneously generating multiple vector light beams

The invention discloses a device and a method for simultaneously generating a plurality of vector light beams, the device comprises a Gaussian light source, a polarization converter, a beam expanding device, a plurality of arbitrary structure vector light beam generating devices and a detection device, the plurality of arbitrary structure vector light beam generating devices are internally provided with spatial light modulators (SLMs) and a beam displacer (BD), and the detection device is connected with the Gaussian light source, the polarization converter, the beam expanding device, the plurality of arbitrary structure vector light beam generating devices and the detection device. According to the method, a plurality of vector light beams of any structure can be generated at the same time only through a single digital hologram without the help of any specially processed optical element, and the results have potential application prospects in related fields such as tiny particle control and quantum optics.
