我们描述了一种惯性测量装置的基础上电动捕获的检验质量。机械约束被取代的指导领域，允许陷阱的刚度进行动态调整。检测质量块运动的光学读出提供加速度和旋转的测量，从而产生集成的六自由度惯性测量装置。我们展示了这样一个设备，构造没有微加工与商业微机电系统技术的灵敏度相媲美，并显示如何捕获参数可以调整，以增加动态范围。
We describe an inertial measurement device based on an electrodynamically trapped proof mass. Mechanical constraints are replaced by guiding fields, permitting the trap stiffness to be tuned dynamically. Optical readout of the proof mass motion provides a measurement of acceleration and rotation, resulting in an integrated six degree of freedom inertial measurement device. We demonstrate such a device-constructed without microfabrication-with sensitivity comparable to that of commercial microelectromechanical systems technology and show how trapping parameters may be adjusted to increase dynamic range.
