| 1. A method for measuring properties of a sample comprising:
providing a cantilever comprising a tip;
interacting the tip with a sample;
imparting a series of temporary driving signals to the cantilever;
recording a series of transient cantilever responses corresponding to the driving signals;
coherently averaging the series of transient cantilever responses; and,
extracting frequency and decay time information from averaged transient responses.
