Phase Imaging (AC Mechanical Contrast)
Visualizing Nanoscale Mechanical Properties
Phase Imaging, also known as AC Mechanical Contrast, is a powerful Atomic Force Microscopy (AFM) mode used to map material properties like stiffness, adhesion, and viscoelasticity. By analyzing the phase shift of the oscillating probe, this mode reveals nanoscale variations in mechanical contrast, making it ideal for materials science, polymers, and nanotechnology applications.
