基于Unity 3D的三维虚拟分光计仿真系统的开发

Development of Three-Dimensional Virtual Simulation for Spectrometer Based on Unity 3D

摘要: 分光计的调节与使用是基础物理实验中教师难教，学生难学的一个实验。为了提高该实验的教学效果，我们开发了基于Unity 3D的三维虚拟分光计仿真系统，实现了分光计中最难学习的同轴等高调节的虚拟仿真。学生利用该系统，不仅可在三维空间中直观地认知分光计各部件的构造及其对应的物理原理，也可以模拟操作分光计，练习同轴等高的调节。教师利用该系统，在课堂教学中可以更有效地讲解分光计的调节。仿真系统的虚拟及增强现实功能显著降低了学生学习分光计的难度，大幅提高了预习效果，有利于教师教学及学生课堂实际操作的开展。我们同时开发了移动端版本，进一步方便了学生的使用。

Abstract: Operation and adjustment of spectrometer are a difficult basic experiment for teachers and students. To promote the classroom teaching effect, we developed a three-dimensional virtual simulation for spectrometer, in which virtual simulation of the most difficult coaxial isohypse adjustment was implemented. By using this software, the students can not only get an intuitive knowledge of the structure of each component of spectrometer and the corresponding physics, but also operate the spectrometer to practice the coaxial isohypse adjustment. Also, the teachers can explain the principles of regulation more effectively in the classroom teaching. Thus the virtuality and augmented reality of this software significantly decrease learning difficulty and improve the preview effect, which is benefit for teaching and in-class operation. We also developed the mobile version which further facilitates students to use the software.
