摘要:

我们提出了一个紧凑的单片光机械惯性传感器的性能分析,描述了其关键的基本限制和整体加速度噪声地板。低频重力敏感惯性传感器的性能仿真表明,加速度噪声本底可以达到10^-11 ms^-2/rtHz的量级。此外,从我们的性能模型,我们确定在我们的传感器设计,灵敏度和带宽贸易空间的优化标准。我们对这些紧凑型机械谐振器进行了表征测量,展示了250 kg级别的mQ产品,突出了其精致的加速度灵敏度。

英文摘要:

We present a performance analysis of compact monolithic optomechanical inertial sensors that describes their key fundamental limits and overall acceleration noise floor. Performance simulations for low frequency gravity-sensitive inertial sensors show attainable acceleration noise floors of the order of 10^-11 ms^-2/rtHz. Furthermore, from our performance models, we determine the optimization criteria in our sensor designs, sensitivity, and bandwidth trade space. We conducted characterization measurements of these compact mechanical resonators, demonstrating mQ-products at levels of 250kg, which highlight their exquisite acceleration sensitivity.
