光力惯性传感技术是利用光子与机械振子的相互作用,通过出射光的动量和角动量的变化实现对振子运动状态的监测,进而实现对其受力(矩),以及(角)速度、(角)加速度测量的新型惯性传感技术。该技术既有高极限精度的原理优势,又有微型化的技术优势,是惯性传感技术的前沿领域,具有极大的发展潜力。首先介绍了基于光阱系统和微腔系统的两类光力惯性技术,分析了其基本工作原理与物理特征;其次介绍了国内外光力惯性传感器件的研究现状;最后对光力惯性技术的发展特点、国内外差距进行了总结,并给出了我国发展光力惯性传感技术的建议。

In an optomechanical system,photons and the mechanical oscillators act on each other,and the motion of the oscillators can be monitored by the change of momentum or energy of the light.The optomechanical inertial sensing technology uses this principle to realize the measure-ment of the force/torque,the linear/angular velocity and the linear/angular acceleration.Combining the advantages of high limit accuracy and miniaturization,this technology is one of the frontiers in the field of inertial sensing technology with extreme development potential.First the basic principles and characteristics of the optomechanical inertial sensing technology based on optical trapping system and microcavity system are introduced,followed by their research status.Afterwards the development characteristic of this technology and the gap between domestic and overseas organizations are summarized.Some suggestions about the domestic development of inertial sensing technology are made in the end.
