    摘要: A method, a system and a computer readable medium for dynamic mode AFM amplitude versus distance curve acquisition. In an embodiment, a constant force feedback mechanism is enabled prior to the first time an AFM probe tip contacts a sample. The feedback mechanism setpoint is iteratively reduced while at least phase and amplitude of the probe tip are recorded as a function of the relative z-height of a cantilever coupled to the probe tip. The feedback mechanism setpoint may be repeatedly swept between upper and lower bounds to average out drift between the cantilever and sample. Upon detecting a threshold, an absolute tip-to-sample distance is determined and correlated to the relative z-heights. The amplitude and phase data recorded prior to tip-sample contact is then determined as a function of absolute tip-to-sample distance.
