摘　　要：在激光谐振腔实验教学中,经常出现学生在短时内难以完成实验、教学成本高昂、教学过程存在安全隐患等问题,对此利用Unity 3D引擎与Vuforia,运用VR、AR等扩展现实技术,开发了激光谐振腔实验教学虚拟仿真系统。该系统适用于PC端、移动端、Web端多种平台,贯穿实验教学过程中预习、练习、复习、考核与评价等阶段,构建形成实验教学闭环。据系统使用数据与学生反馈意见,该系统能降低教学成本,提高实验室教学效率,减少实验教师教学压力,激发学生学习兴趣。In view of the problems in the experiment teaching of laser resonator,such as the difficulty of students to complete the experiment,the high cost of teaching,and the hidden danger in the teaching process,etc.,this paper develops an auxiliary teaching system based on Unity 3D engine and Vuforia of laser resonator experiment by using virtual reality,augmented reality and other extended reality technologies.The system covers PC,mobile and Web platforms,runs through the stages of preview,practice,review,assessment and evaluation in the process of experimental teaching,and constructs a closed-loop experimental teaching.By analyzing the data and students’feedback of the system,it shows that the system can reduce the teaching cost,improve the efficiency of laboratory teaching,reduce the teaching pressure of experimental teachers,and stimulate students’interest in learning.
