产生具有复杂空间分布的矢量光场在需要奇异光场的领域中具有极大的兴趣，包括粒子操纵、光学纳米加工、光束成形和光学成像。本文设计、制作并测试了一台能够产生任意复杂光束截面的矢量光场发生器。基于两个反射式纯相位液晶空间光调制器，该发生器能够逐像素地控制光场的空间分布的所有参数，包括相位、振幅和偏振（椭圆率和取向）。成功地产生了包含相位，幅度和/或偏振调制的各种光场，并使用斯托克斯参数测量进行测试，以证明这种光场发生器的能力和多功能性。(C)2013年美国光学学会
Generation of vectorial optical fields with complex spatial distribution in the cross section is of great interest in areas where exotic optical fields are desired, including particle manipulation, optical nanofabrication, beam shaping and optical imaging. In this work, a vectorial optical field generator capable of creating arbitrarily complex beam cross section is designed, built and tested. Based on two reflective phase-only liquid crystal spatial light modulators, this generator is capable of controlling all the parameters of the spatial distributions of an optical field, including the phase, amplitude and polarization (ellipticity and orientation) on a pixel-by-pixel basis. Various optical fields containing phase, amplitude and/or polarization modulations are successfully generated and tested using Stokes parameter measurement to demonstrate the capability and versatility of this optical field generator.
