光学衍射仿真实验系统的设计

摘  要

 计算机技术是人类智慧的结晶，它正在以十分迅猛的速度进步中。21世纪的课堂，计算机辅助教学以其灵活、生动、形象、鲜明的文字、声音、图形和动画等丰富多彩的表现形式，使物理实验教学内容丰富多彩，形象易懂。
 光学实验教学引进计算机仿真技术，使其不受实验仪器和实验场所的限制，可以通过改变实验参数获得不同的实验结果，方便教师课堂演示，使课堂教学内容形象化，表现手段多样化，创造一个生动活泼的学习氛围，让我们能够结合形象的实验现象更加深刻理解光学理论。开发光学实验的仿真模拟系统，并将其运用到物理光学的教学和实验当中，对大学光学实验的现代化发展有着深远的意义。
 论文分为以下几个部分：
 首先，简单地介绍了光学衍射的基本原理和类型及其性质，还有光学衍射技术的应用和发展。
 其次，介绍光学衍射实验系统的基础知识，包括光学衍射实验系统的结构组成，操作方法，还有衡量参数等。
 再次，介绍了光学衍射仿真实验系统的原理，特点，发展现状及其应用，给出光学衍射仿真实验系统设计的理念和方法。
 最后，介绍光学衍射仿真实验系统的设计过程，以及应用到的关键技术和攻克的难题，还有系统的应用前景和意义。
 本设计采用Matlab与 Visual Basic 混合编程的技术，结合了Matlab强大的矩阵运算能力和VB制作人机界面的优势，运算速度快，界面简洁好看，操作简单，方便应用于光学实验教学之中。

Design on optical diffraction simulation experiment system

ABSTRACT

 Computer technology is the crystallization of human intelligence, it is very rapid speed improvement. The 21st century classroom, computer aided teaching by its flexible, vivid, image, distinct words, sound, graphics and animation, and other rich and colorful forms, make physical experiment teaching content rich and colorful, the image is understandable.
 Optical experimental teaching introducing computer simulation technology, make its from experimental instruments and experimental site limitation, can obtain different experimental parameters by changing the experimental results, convenient teacher's classroom demonstration, makes the classroom teaching content visualization, performance means diversification, creating a lively atmosphere, let us can combine the experimental phenomena image more profound understanding optical theory. Development of the simulation system for optic experimental, and was applied to physical optics of teaching and experiments, the modernization of optics laboratory of university development has a profound significance.
 Paper is divided into the following several parts:
 First of all, simply introduces the basic principle and optical diffraction type and nature and the prospect of diffractive optical technology.
 Secondly, introduce optical diffraction experiment system of knowledge, including optical diffraction experiment system structure, operation methods, and measuring parameters etc.
 Again, introduced the optical diffraction simulation experiment system of principle, characteristics, development situation and its application, give optical diffraction simulation experiment system design ideas and methods.
 Finally, simulation experiment system introduced the optical diffraction of design process, and the key technology and application to conquer difficulties, and system application prospect and meaning.
 This design USES the Matlab and Visual Basic mixing programming technology, combined with Matlab powerful matrix computation ability and VB the advantage of making human-machine interface, quick speed, the interface is simple good-looking, simple operation, convenient application of YuGuangXue experiment teaching.
Keywords: computer simulation  optical diffraction experiment  Matlab  mixing programming
