Inertial Sensing Disruptive Technology Based on Levitated Optomechanics
悬浮光力学是光力学与量子光学结合的产物，为微纳机械振子的控制和测量提供了一种全新的量子方法，这种方法具有前所未有的观测精度，可接近甚至突破标准量子极限，具有广阔的发展和应用前景。目前国际上已在室温下利用此系统实现了力、力矩、位移、加速度等多个物理量的极高灵敏度测量。本文综述了悬浮光力学的研究现状及国内外在精密传感与测量方面的进展。作为近年来发展起来的一种前沿技术，悬浮光力学已逐渐从基础研究走向应用，特别是对惯性传感与精密测量领域有重要的应用前景。最后提出了发展基于悬浮光力学的惯性传感颠覆性技术的建议，为我国惯性传感与量子精密测量技术发展规划的制定提供参考。
Levitated optomechanics is the combination of optomechanics and quantum optics. It provides a new quantum method to control and measure micro-nano mechanical oscillator. This method has unprecedented observation accuracy, can approach or even break the standard quantum limit, and has broad development and application prospects. At present, the system has been used to measure the force, torque, displacement, acceleration and other physical parameters with high sensitivity at room temperature. In this paper, the research status of levitated optomechanics and its progress in precision sensing and measurement are reviewed. As a frontier technology developed in recent years, levitated optomechanics has gradually moved from basic research to application, especially in the field of inertial sensing and precision measurement. Finally, suggestions for developing the inertial sensing disruptive technology based on levitated optomechanics are put forward, which can provide reference for the development planning of inertial sensing and quantum precision measurement technology.
