摘要

微磁场测量在许多科学领域中具有重要的应用价值,现有大学物理实验教学相关仪器比较固定,不利于学生开展进一步实验探索.结合莫尔条纹的放大特性,通过观测莫尔条纹在磁场中的变化规律,建立两者之间的定量关系,实现基于莫尔条纹技术的微磁场测量. 进一步改变光栅常数,研究其对测量结果的影响,并利用Image J软件对图像数据进行采集,优化基于莫尔条纹技术的微磁场测量系统. 该测量方法具有可视化、操作简单、设备易组装等优点,便于让学生在掌握微磁场特性的同时,进一步实施相关拓展研究.

Abstract

Micromagnetic field measurement has shown significant application value in many scientific fields. However, existing instruments for physics experiments in university are relatively rigid, limiting students' opportunities to conduct further experimental exploration. By leveraging the amplification characteristics of Moiré fringes, the variation patterns of Moiré fringes under magnetic fields was observed and established a quantitative relationship between them, enabling micromagnetic field measurement based on Moiré fringe technology. Furthermore, by modifying the grating constant, the influence on the measurement results was investigated. The Image J software was utilized to collect and analyze image data, optimizing the micromagnetic field measurement system based on Moiré fringe technology. This measurement method offers the advantages of visualization, ease of operation, and straightforward equipment assembly, enables students to both understand the characteristics of micromagnetic fields and pursue extended research projects.
