基于Labview的光学空间滤波远程虚拟实验

Remote Virtual Experiment of Optical Spatial Filtering Based on Labview

提出了一种利用Labview实现光学空间滤波模拟的新方法,并对经典的阿贝-波特实验设计了仿真程序.该程序可根据用户设置的参量生成二维网格光栅作为整个物理过程的输入物,允许用户选择多种不同的滤波方式,如低通、高通、方向滤波等,并可依次操纵成像的各个步骤.程序可脱离编程环境独立运行,具有跨平台、界面友好、易于操作等优点,并可架设基于浏览器的远程虚拟实验.

A new method of using Labview to simulate optical spatial filtering is put forward and a simulation program for classical Abbe-Porter experiment is designed. It can generate 2D grid gratings based on user＇s setting and take them as input objects for the whole physical process. It provides several filtering modes for users to select like low passing,high passing,and directional passing etc. Users can manipulate the imaging process step by step. The program runs independently of programming environment and operating system. It is friendly interfaced and easy to use. Furthermore, constructing a remote virtual experiment based on browsers is possible,which makes it a perfect CAI software for relevant courses.
