摘　　要：对原有的偏振光演示实验装置的光源进行改进,3只光谱连续的白炽灯呈正三角形排列,白炽灯前配有均光板,增加了光源的均匀性.实验装置配备底座和充电电源,更适合在普通教室做演示实验.改进的装置可以演示光是横波、偏振光干涉和光弹性效应.The light source of the polarized light demonstration experiment was improved,three incandescent lamps with an equalizing plate were arranged in a triangle to increase the uniformity of the light source,and the experimental device was equipped with a pedestal and a rechargeable power supply,which was more suitable for demonstration in classroom.Using the improved device,the transverse wave characteristics of light,polarized light interference and photoelastic effect were demonstrated.

关 键 词：偏振 偏振光干涉 光弹性效应
