Design and Implementation of a Python-based Software for High Field Magneto-Imaging System

Many scientific researches require the observation of microscopic images of samples under high magnetic fields. Due to the strong effect of high magnetic fields on magnetic materials and electronic devices, such microscopy imaging system is completely different from conventional systems. In order to control of the imaging system and the acquisition of microscopic image data under high magnetic fields, we developed a control software based on Python. This software provides functionalities such as monitoring the magnet status, controlling piezoelectric displacement devices, and real-time image monitoring. It further use an automatic focusing algorithm, in conjunction with piezoelectric displacement devices, to automatically focus optical images under high magnetic fields. Experimental results indicate that this software is capable of imaging samples under magnetic fields, thereby laying the foundation for the exploration of microscopic changes in samples under high magnetic field conditions.
