将空间光调制器（SLM）引入光学操纵系统。SLM的实时可重构特性使得无需光学部件的机械运动即可对微粒子进行光学操作成为可能。在系统中加入液晶SLM形成菲涅耳带板（FZP）。FZP产生的光束光斑通过还原光学在样品溶液上成像。样品溶液中的微粒被束流捕获，并通过从计算机改变FZP到SLM的寻址位置来控制。首次证明了微粒子的非机械光学操纵。
A spatial light modulator (SLM) is introduced to an optical manipulation system. The real-time reconfigurable feature of the SLM makes it possible to perform an optical manipulation of microparticles without mechanical movements of optical parts. A liquid crystal SLM incorporated in the system forms a Fresnel zone plate (FZP). The beam spot generated by the FZP is imaged on a sample solution by reduction optics. A microparticle in the sample solution is trapped by the beam and manipulated by changing the addressing position of the FZP onto the SLM from a computer. The nonmechanical optical manipulation of microparticles is demonstrated for the first time.
