基于虚拟现实的超快激光实验仿真系统探索

Research on Ultra-fast Laser Experiment Simulation System Based on Virtual Reality

为了解决在实际开设超快激光实验时成本高、危险大等问题,以及利用虚拟现实技术诸多的优点,该文对基于虚拟现实的超快激光实验仿真系统进行探索研究。在分析超快激光实验内容和技术要求的基础上,以虚幻引擎(Unreal Engine 4)作为主要开发平台,实现了场景建模、实验仪器设备建模、用户界面设计等,设计并提供了二维、三维交互接口,可利用键盘、数据手套等交互设备进行操作,可用普通显示器、可也用头盔显示器显示。测试表明,此仿真实验系统操作简单,画面形象,有助于学生理解超快激光实验的原理和机制,提高实验教学质量和效率。

In order to resolve the problems of high cost and high risk in the actual opening of ultra-fast laser experiments,and the advantages of using virtual reality technology,this paper explores the ultra-fast laser experimental simulation system based on virtual reality.Based on the ultra-fast experiment content and technical requirements,Unreal Engine 4 is the main development platform.Scene modeling,experimental instrumentation modeling,user interface design,etc.are realized.And 2D/3D interfaces are designed and provided for the interaction with keyboard,and data gloves,and can be displayed by an ordinary display or a helmet display.Test shows that the simulation system is simple in operation and has a picture image,which helps students understand the principles and mechanisms of ultrafast laser experiment and improve the quality and efficiency of experimental teaching.
