报道了一种精确旋转单胞的方法。在这种方法中，光轴方向的光压力被利用为旋转扭矩。每个电池中的两个近点使用两束光束从不同的方向照明，并产生一个作为旋转扭矩的光压力。使用这种方法，我们可以控制微球的旋转方向，而不考虑非接触操作中的折射率分布。利用近端双光束光钳可以实现微球的旋转，通过改变光强来控制微球的旋转速度。
A precise method to rotate single cells is reported. In this method, the light pressure in the optical axis direction is harnessed as a rotating torque. Two proximal points in each cell are illuminated from different directions using two beams, and a light pressure is created that acts as a rotating torque. Using this proposed method, we could control the rotational direction of a microsphere regardless of the refractive index distribution in a noncontact operation. The microsphere could be rotated using proximal two-beam optical tweezers, and the rotational velocity could be controlled by changing the light intensity.
