提出了一种利用高Q值微球回音壁模式谐振器的加速度传感新概念。诱导的弯曲臂位移监测通过耦合到弯曲的球形光学腔的谐振特性的变化。瞬时测量灵敏度优于1毫克，在250赫兹的带宽，和100马克杯的噪声地板证明。(C)2001 Elsevier Science B.V.保留所有权利。
A novel acceleration sensing concept utilizing high-Q microsphere whispering-gallery mode resonators is presented. Induced flexure-arm displacements are monitored through changes in the resonance characteristics of a spherical optical cavity coupled to the flexure. Instantaneous measurement sensitivity of better than 1 mg at 250 Hz bandwidth, and a noise floor of 100 mug are demonstrated. (C) 2001 Elsevier Science B.V. All rights reserved.
