Abstract
We introduce and demonstrate a method of measuring small force gradients acting on a harmonic oscillator in which the force-gradient signal of interest is used to parametrically up-convert a forced oscillation below resonance into an amplitude signal at the oscillator's resonance frequency. The approach, which we demonstrate in a mechanically detected electron spin resonance experiment, allows the force-gradient signal to evade detector frequency noise by converting a slowly modulated frequency signal into an amplitude signal.
摘要
我们介绍并演示了一种测量作用于谐波振荡器上的小力梯度的方法，其中感兴趣的力梯度信号用于将低于共振频率的强迫振荡参数性地上转换为振荡器共振频率处的幅度信号。我们在机械检测电子自旋共振实验中演示的这种方法，通过将缓慢调制的频率信号转换为幅度信号，使力梯度信号能够规避探测器频率噪声。
