摘要：
悬浮偶极散射体作为光力学系统在介观尺度量子力学观测中表现出优异性能。然而，它们几乎会向所有方向散射光的特性带来了实验挑战，尤其限制了光收集效率，进而限制了可从系统中提取的信息量。本文提出了一种实验装置，旨在通过将反作用约束在特定空间方向上，提升从光力学测量中获取的信息量。该方法有助于在任意给定数值孔径下实现海森堡极限探测。该装置包含一个中空半球面镜，用于控制偶极发射体散射的光（尤其是大散射角的光），从而聚焦所获取的信息。该反射镜与悬浮光力学领域常用的现有装置（包括共焦透镜和光学谐振腔）兼容。
英文摘要：
Levitated dipolar scatterers exhibit exceptional performance as optomechanical systems for observing quantum mechanics at the mesoscopic scale. However, their tendency to scatter light in almost any direction poses experimental challenges, in particular limiting light collection efficiencies and, consequently, the information extractable from the system. In this article, we present a setup designed to enhance the information gleaned from optomechanical measurements by constraining the back action to a specific spatial direction. This approach facilitates achieving Heisenberg-limited detection at any given numerical aperture. The setup consists of a hollow hemispherical mirror that controls the light scattered by the dipolar emitter, particularly at high scattering angles, thereby focusing the obtained information. This mirror is compatible with existing setups commonly employed in levitated optomechanics, including confocal lenses and optical resonators.
