We have developed a real-space method to correct distortion due to thermal drift and piezoelectric actuator nonlinearities on scanning tunneling microscope images using Matlab. The method uses the known structures typically present in high-resolution atomic and molecularly resolved images as an internal standard. Each image feature (atom or molecule) is first identified in the image. The locations of each feature's nearest neighbors are used to measure the local distortion at that location. The…

A path planning method for real time correction of image distortion in atomic force microscope

The image quality and accuracy of the atomic force microscope are seriously affected due to drift and hysteresis of Piezoelectric positioning platform. Currently, the distortion correction methods

Scanning Imaging Restoration of Moving or Dynamically Deforming Objects

A theory to describe the mechanism of the scanning imaging process and restoration of the degraded image (distorted and blurred image) obtained using an SEM is proposed and it is anticipated that this imaging and restoration theory will enable the scanning Imaging mode to be used in in situ dynamic imaging and for mechanical property measurement of materials.

A method to correct hysteresis of scanning probe microscope images based on a sinusoidal model.

A practical and simple mathematical model derived from experimental phenomenon, which is the combination of sinusoidal and linear functions, was proposed to describe the hysteresis behavior of piezoelectric actuators with repeated scanning and is suitable and easy to be integrated into the scanning program of AFM without requiring hardware modifications.

Extraction of Hidden Science from Nanoscale Images.

Algorithms used to examine the dipole direction of individual molecules and surface domains, hydrogen bonding interactions, and molecular tilt are discussed, which enable researchers to segment images by domains and subdomains, thereby highlighting reactive and interesting disordered sites at domain boundaries.

Three-axis correction of distortion due to positional drift in scanning probe microscopy.

This work presents a technique for correcting distortion due to thermal drift along all three spatial axes, along with simultaneous correction of z-axis piezo creep, and demonstrates that this technique can routinely reduce distortion from these effects by over 90%, often to a precision of better than a single pixel.

Geometrical distortions of scanning tunneling or atomic force microscope pictures can be caused by delayed response of the piezo‐ceramics and errors of the nonlinear feedback system. The images are
