    • A method of operating an atomic force microscope, comprising a probe, the probe being moved forth and back during respective trace and retrace times of a scan line, the method comprising: a) during trace time, oscillating the probe, b) generating a z feedback signal to keep an amplitude of oscillation of the probe constant at a setpoint value, the z feedback signal being generated by a first feedback loop, c) during retrace time, placing the probe in a drift compensation state by changing the setpoint value to a different value so that the z feedback signal being generated by the first feedback loop causes the probe to move away from the sample and oscillate free, d) detecting an amplitude of free oscillation of the probe and adjusting with a second feedback loop its excitation signal to maintain the amplitude of free oscillation of the probe close to a set value.
    • 一种操作原子力显微镜的方法,所述原子力显微镜包括探针,所述探针在扫描线的相应追踪和回扫期间前后移动,所述方法包括:a)在迹线时间期间,振荡 探针,b)产生z反馈信号以保持探针的振荡幅度恒定在设定点值,z反馈信号由第一反馈回路产生,c)在回扫时间期间,将探针置于漂移补偿状态 通过将设定值改变为不同的值,使得由第一反馈回路产生的z反馈信号使得探头从样品移开并自由摆动,d)检测探头的自由振动的振幅并且用 第二个反馈回路激励信号,以保持探头自由振荡的振幅接近设定值。
