摘要：

A differential optical detection method was developed to measure the oscillation amplitude of a quartz timing fork. To implement all optical knife-edge technique, the timing fork had a tiny knife-edged tip attached to one prong of the timing fork and a probe tip to the other. We developed a simplified model based oil a perturbation analysis and directly measured the actual oscillation amplitude of the tuning fork.
