光学干涉仪是研究纳米和微机械谐振器弯曲振动的有力工具。当悬臂式微丝沿沿着远离光轴的方向振动时，干涉信号对于检测其振动可能不是最佳的。在这项工作中，我们确定了最佳的位置，用于检测悬臂式微丝的振动，使用微透镜光纤干涉仪。我们同时考虑了干涉效应和微线的散射效应。使用自制的干涉仪，我们通过测量相对于光轴在各个方向驱动的悬臂式微丝来验证分析。我们的研究结果表明，最佳检测位置强烈依赖于振动的方向。基于这一观察，我们推断出两个悬臂微线的弯曲振动模式的取向。我们的研究结果可能有助于悬臂微线弯曲振动模式的研究及其在检测矢量力方面的应用。光学干涉仪是研究纳微机械谐振器弯曲振动的有力工具。当悬臂式微丝沿沿着远离光轴的方向振动时，干涉信号对于检测其振动可能不是最佳的。在这项工作中，我们确定了最佳的位置，用于检测悬臂式微丝的振动，使用微透镜光纤干涉仪。我们同时考虑了干涉效应和微线的散射效应。使用自制的干涉仪，我们通过测量相对于光轴在各个方向驱动的悬臂式微丝来验证分析。我们的研究结果表明，最佳检测位置强烈依赖于振动的方向。基于这一观察，我们推断出两个悬臂微线的弯曲振动模式的取向。研究结果对悬臂微线的弯曲振动模式及其应用具有一定的参考价值。
Optical interferometers are powerful tools for studying the flexural vibrations of nano- and micro-mechanical resonators. When a cantilevered microwire vibrates along a direction away from the optical axis, the interference signal may not be optimal for detecting its vibrations. In this work, we identify the optimal locations for detecting the vibrations of a cantilevered microwire using a micro-lens fiber-optic interferometer. We take both the interference effect and the scattering effect of the microwire into account. Using a home-built interferometer, we verify the analysis by measuring a cantilevered microwire driven in various directions with respect to the optical axis. Our results show that the optimal detecting location strongly depends on the orientation of the vibrations. Based on this observation, we inferred the orientations of the flexural vibrational modes of two cantilevered microwires. Our results may be useful in studying the flexural vibration modes of cantilevered microwires and their applications in detecting vectorial forces.Optical interferometers are powerful tools for studying the flexural vibrations of nano- and micro-mechanical resonators.
