太赫兹时域光谱仪虚拟仿真平台设计

Design of Virtual Simulation Experiment Platform for Terahertz Time-Domain Spectrometer

太赫兹波段作为全光谱波段内唯一尚未完全开发的波段,其特性具有极大的科学研究价值和教学意义。太赫兹时域光谱仪是实现该波段光谱表征的仪器,同时也是实现全光谱探测的重要组成。本文采用3D Studio Max、WebGL、AR等技术设计开发了包括实验导读与虚拟仿真实验操作等内容在内,兼具演示教学、交互式仿真练习、操作考评和交流研讨四大核心功能的太赫兹时域光谱仪虚拟仿真实验平台。该平台科学实用、仿真还原度高且不受时空限制,为传统实验教学做出了重要补充。在优化实验教学方式、改善教学效果、探索线上+线下混合式教学模式,促进虚拟仿真技术与太赫兹领域的深度融合等方面起到了重要作用。

The terahertz band is the only band that has not yet been fully developed within the full-spectrum band,and its spectral characteristics have great teaching and scientific research value.The terahertz time-domain spectrometer,as a detection tool,is also an important component of spectroscopy experiments.This article uses 3D Studio Max,Unity3D,WebGL,AR and other technologies to design and develop a virtual simulation experimental platform for terahertz time-domain spectrometers,which includes experimental reading and virtual simulation experimental operations.It also has four core functions:demonstration teaching,interactive simulation exercises,operation evaluation,and communication and discussion.The platform is scientific and practical,with a high degree of simulation reduction,and is not limited by time and space.It has made an important supplement to traditional experimental teaching.It has played an important role in optimizing experimental teaching methods,improving teaching effects,and promoting the deep integration of virtual simulation technology and the field of terahertz.
