摘要
依据马吕斯定律,利用Matlab进行模拟,分析自然光透过不同数量的理想偏振片后的光强变化的规律.结果表明,在每相邻两块偏振片之间角度一致的情况下,插入的偏振片数量越多,透射光的光强反而越强.当插入的理想偏振片数量趋近于无穷时,其透射光强与自然光透过一块偏振片时的光强相同.
With the Marius theorem,we used Matlab to simulate and analyze the variation of the intensity of the natural light which went through different quantities of ideal polarizing films.The result shows that when the angles between the each polarizing films are the same,the more polarizing films we have,the stronger the intensity of light we will get.If the number of polarizing films is close to infinity,the light which has gone through all the polarizing films has the same intensity with the light which has gone through one piece of polarizing film.
