摘要: An improved wedge calibration method for quantitative lateral force measurement in atomic microscopy is presented. The differs from the original one several aspects. It utilizes a much simpler, commercially available, grating and can be performed at any single specified applied load. enables of all types probes, both integrated with sharp tips, colloidal radius curvature up to 2 μm. also simplifies considerably calculation factor by using flat facets on cancel out system errors. A scheme data processing on-line
