摘要
光镊技术具有无机械接触与高精度操纵微小尺度粒子的优点,自发明以来已逐渐成为生命科学和胶体物理学等领域中强有力的研究工具。随着研究的深入,传统的单光阱光镊已难以满足更高级的应用需求。近年来,空间光场调控技术通过对光场的振幅、相位和偏振态分布的调制,极大地丰富和增强了光学微操纵技术的功能,促进了包括激光微纳加工、微粒分选与输运、胶体粒子物理特性研究等方面的发展。从光场的振幅、相位和偏振态调制技术出发,综述近年来空间光场调控技术的发展及其在光学微操纵中的应用,重点介绍全息光镊、特殊模式光束微操纵、矢量光场微操纵等光学微操纵技术的研究进展。
Abstract
Optical tweezers has become a powerful tool for research in life science and colloidal physics since its invention due to its advantages of mechanical contact-free and high-precision manipulation of micro-sized particles. However, the conventional single-trap optical tweezers is limited in the increasing demands of research. In recent years, the technique of spatial modulation of optical fields, which modulates the amplitude, phase and polarization state of light, has extensively enhanced the function of optical micro-manipulation, and promoted the advance in laser micro/nano fabricaton, optical sorting and transportation of micro-particles, and colloidal particles studies. The advance in spatial modulation of optical fields to date and their applications in optical micro-manipulation is reviewed, including the holographic optical tweezers, special-mode optical beams manipulation, and vector beams manipulation.
