Computerized Image Analysis Software for Measuring Indents by AFM
Indentation testing measures the mechanical properties of materials from the nanoscale to microscale. An atomic force microscope can be used to image the residual indent. However, it is difficult to measure the indentation from a complex three dimensional image, therefore automated software was developed to measure the depth, projected area and effective surface area. This software digitally reconstructs the fully loaded indentation shape from the residual indent image. The contact depth, contact area, indenter angle and tip radius are measured from the reconstructed image.
