真空中的悬浮光学力学在包括量子力学和重力在内的物理学的基本测试、传感弱力或加速度以及精确测量方面显示出了希望。虽然许多研究都集中在介电粒子的光学捕获上，但其他方法，如反磁粒子的磁捕获，也引起了人们的兴趣。在这里，我们回顾了光和磁在真空中捕获的几何结构，重点讨论了对于直径至少为1微米的粒子的陷阱的性质。
Levitated optomechanics in vacuum has shown promise for fundamental tests of physics including quantum mechanics and gravity, for sensing weak forces or accelerations, and for precision measurements. While much research has focused on optical trapping of dielectric particles, other approaches, such as magnetic trapping of diamagnetic particles, have been gaining interest. Here we review geometries for both optical and magnetic trapping in vacuum, with an emphasis on the properties of traps for particles with a diameter of at least one micrometer.
