摘要偏振光是指光矢量的振动方向不变，或具有某种规则地变化的光波。按照其性质,偏振光又可分为平面偏振光（线偏振光）、圆偏振光和椭圆偏振光、部分偏振光几种。偏振光理论在地质学、地震学、天文学等方面都有广泛应用。27676
本文主要介绍了和偏振光理论相关的三个实验，通过实验加深对光的偏振理论的了解，三个实验分别为观察线偏振光并验证马吕斯定律、测量布儒斯特角以及椭圆偏振光的检测。由于实验中测得的数据量较大，需要花费较多的时间进行处理。为了提高数据分析的效率，设计并开发了一款基于跨平台C++图形用户界面应用程序开发框架Qt的软件用于处理实验数据。该软件包括数据输入、数据分析处理以及绘制曲线三大功能，达到即时处理实验数据、判断数据正误、找出错误原因的功能。

Title Analysis of the experimental principle and experimental data of polarized light study on software
Abstract
Polarized light refers to the vibration direction of light vector invariant, or the light that change with some rules. According to its nature, polarized light can be pided into several types such as plane polarized light (linear polarized light), circularly polarized light elliptically polarized light,and partially polarized light.The theory of geology is widely used in the area of seismology, astronomy, polarized light and so on.
This paper mainly introduces three experiments about theory of polarized light, it has deepen the understanding of light polarization theory through experiments.The three experiments are as follow:observing the linearly polarized ligh,verifying Malus law, measuring Brewster angle and elliptically polarized light detection.Due to the large amount of data in this experiment, it costs more time to deal with. In order to improve the efficiency of data analysis, the author design and develop the software that based on a cross platform C++ graphical user interface application development framework QT, to deal with the data in this experiment.This software has three functions including data input,data analysis,processing and curve drawing,it can deal with experimental data on time, judge whether the data is right or wrong as well as find out the cause of error.
Keywords: polarized light, Marius law, Brewster angle, ellipsometry, software design
