光学虚拟实验室中典型光路调试的仿真实现

Simulation and Implementation of Typical Optical Path Adjustments Involved in an Optical Virtual Lab

在Visual Studio2005下,将面向对象的方法应用于虚拟器材建模,基于C#编写"事件驱动"型应用程序以仿真各种实验场景和实验状态。通过操作鼠标和键盘,可以进行使激光光束平行于工作台面、使激光光束的主光线通过透镜光学面中心、使针孔位于扩束镜后焦点处,基于剪切干涉法使透过准直透镜的激光为平行光、使光栅光谱仪中的光栅位于与光轴垂直的平面内并且栅线平行于狭缝5种典型光路的交互式实时虚拟调试。这种所见即所得的虚拟实验方式无需真实实验设备支撑,有助于增强感性认识,加深对光学基础理论的理解。

To avoid the limits of traditional optical real lab on the opening hours,space and equipments,an object-oriented approach was applied to the modeling of virtual equipments and the simulation of various experimental scenes and status were realized through developing of ＂event driven＂ applications based on C# language in Visual Studio 2005.Real-time interactive virtual adjustments of optical paths which include adjusting the laser beam to be parallel to the work platform,adjusting the chief ray of the laser beam to go through the center of the lens optical surface,adjusting the pinhole to position in the focus of the extender lens,adjusting the collimating lens based on shearing interferometry to get collimated laser beam,adjusting the grating in spectrometer to locate in the plane perpendicular to the optical axis and the grating line to be parallel to the slit,could be simulated through operations of the mouse and keyboard.This WYSIWYG way of virtual experiment needs no real experimental equipment support,can realize concept of ＂if users can＇t come to the lab…,the lab without walls will come to users!＂,is helpful to enhance perceptual knowledge and deepen the understanding of the optical basic theory.
