光电镊子（OET）是一种有用的光学微操作技术，已在电气工程和生物医学工程的细胞选择中得到广泛应用。在这项工作中，我们研究了使用不同形状和厚度的光模式来操纵OET的介电微粒。结果表明，随着光模厚度的增加，微粒的最大速度先增大到一个峰值，然后逐渐减小。数值模拟是为了阐明潜在的物理机制
Optoelectronic tweezer (OET) is a useful optical micromanipulation technology that has been demonstrated for various applications in electrical engineering and most notably cell selection for biomedical engineering. In this work, we studied the use of light patterns with different shapes and thicknesses to manipulate dielectric micro-particles with OET. It was demonstrated that the maximum velocities of the microparticles increase to a peak and then gradually decrease as the light pattern ’ s thickness increases. Numerical simulations were run to clarify the underlying physical mechanisms
