我们提出并演示了使用基于莫尔条纹的旋转光镊来捕获和旋转微粒和生物样品。我们证明，聚苯乙烯珠以及大肠杆菌细胞可以轻松旋转，而旋转的速度和方向可以完全由计算机控制，从而避免了机械运动或相敏干扰。此外，我们通过实验演示了白光推进光束和阵列的生成，并讨论了基于不相干白光旋转图案的光镊和粒子微操纵的可能性。
We propose and demonstrate trapping and rotation of microparticles and biological samples with a moiré-based rotating optical tweezers. We show that polystyrene beads, as well as Escherichia coli cells, can be rotated with ease, while the speed and direction of rotation are fully controllable by a computer, obviating mechanical movement or phase-sensitive interference. Furthermore, we demonstrate experimentally the generation of white-light propelling beams and arrays, and discuss the possibility of optical tweezing and particle micro-manipulation based on incoherent white-light rotating patterns.
