摘要

悬浮光学机械系统是力和加速度传感的绝佳候选平台。我们提出了一种利用光悬浮纳米粒子阵列的力传感协议。在我们的方案中,使用全息光镊将 N 个纳米粒子困在一个光腔中。外部激光器驱动空腔,激发 N 个空腔模式同时与 N 个纳米粒子相互作用。光机械相互作用将作用在每个纳米粒子上的力的信息编码为腔内光子,这些光子可直接在腔的输出端口检测到。因此,我们的方案可以实现力场的实时成像。

Imaging a force field via an optically levitated nanoparticle array
Levitated optomechanical systems represent an excellent candidate platform for force and acceleration sensing. We propose a force-sensing protocol utilizing an optically levitated nanoparticle array. In our scheme, N nanoparticles are trapped in an optical cavity using holographic optical tweezers. An external laser drives the cavity, exciting N cavity modes interacting simultaneously with the N nanoparticles. The optomechanical interaction encodes the information of the force acting on each nanoparticle onto the intracavity photons, which can be detected directly at the output ports of the cavity. Consequently, our protocol enables real-time imaging of a force field.
