我们调查的控制程度，可以行使一个光学捕获的微观非球形力探针。通过以不同的方式对平移和旋转模式进行位置夹紧，我们能够在不降低灵敏度的情况下显著提高探头的位置分辨率。我们还展示了旋转平移耦合的控制，并展示了一种机制，使探针的平均旋转中心可以从其中心移位。
We investigate the degree of control that can be exercised over an optically trapped microscopic non-spherical force probe. By position clamping translational and rotational modes in different ways, we are able to dramatically improve the position resolution of our probe with no reduction in sensitivity. We also demonstrate control over rotational-translational coupling, and exhibit a mechanism whereby the average centre of rotation of the probe can be displaced away from its centre.
