摘要

近年来，真空光学阱悬浮粒子在精密传感器开发和新物理探索方面显示出巨大的潜力。然而，传感器的精度仍然受到与被捕获粒子的绝对位移有关的校准因子的不确定性的影响。本文提出并实验证明了一种基于真空中自由落体粒子的光镊标定新方法，其中引入了重力加速度作为绝对参考。我们的工作提供了一种具有高度确定性和可追溯性的校准方案，这对提高基于悬浮光学机械系统的精密传感精度具有重要意义。

Displacement Calibration of Optical Tweezers With Gravitational Acceleration

Abstract In recent years, levitated particles of optical traps in vacuum have shown the enormous potential for precision sensor development and new physics exploration. However, the accuracy of the sensor is still hampered by the uncertainty of the calibration factor relating the detected signal to the absolute displacement of the trapped particle. In this paper, we suggest and experimentally demonstrate a novel calibration method for optical tweezers based on free-falling particles in vacuum, where the gravitational acceleration is introduced as an absolute reference. Our work provides a calibration protocol with a great certainty and traceability, which is significant in improving the accuracy of precision sensing based on levitated optomechanical systems.
