Scanning probe microscopes are used to image sample surfaces at the nano to atomic level. Until now, precise measurements were conducted under ultra-high vacuum and extreme low-temperature environments. Recently, capturing phenomena occurring at room temperature, such as surface diffusion, surface dynamics, biological observations, and drug reactions, has become important. However, at room temperature, thermal drift causes the imaging area to shift, making long-term observation of changes in the same region at the nanometer scale very challenging. In this study, we report the development of an automatic correction technique for thermal drift using feature point matching.
