摘要
提高测角系统的测量分辨率以及测量范围对于角度测量技术的发展至关重要。与传统的旋转棱镜的测角方法相比,文中提出的基于激光自混合干涉技术的微角度测量实验装置结构简单,成本较低,并且可以在扩大角度测量范围的同时,提高微角度测量分辨率,有效加深学生对于微角度测量的理解。通过将科研最新进展引入实验教学环节所提出的探究性实验可以丰富大学物理实验的教学内容,对于培养学生的科研素养,以及对于提高学生的主动探究能力都能够起到实质性的作用。
Improving the resolution and range of angle measurement systems is crucial for the development of angle measurement technology.Compared with traditional angle measurement methods using rotating prisms,the proposed small-angle measurement experimental device based on laser self-mixing interference technology is simple in structure and low in cost,and can improve the resolution of small-angle measurement while expanding the angle measurement range,and effectively deepen students’understanding of small-angle measurement.By introducing the latest progress of scientific research into experimental teaching,the designed exploratory experiments can enrich the teaching content of college physics experiments,and play a substantial role in cultivating students’scientific research literacy and improving their proactive exploration ability.
