摘　　要：通过硅光电池接收偏振光强分布变化和数字显示器接收角度传感器的角度变化电信号,直观地显示出椭圆偏振光的光强变化波形和数字读数,并通过仪器直接拟合和计算软件画图分别得出椭圆偏振光图形,实验结果与理论计算值相符合.The intensity distribution of the polarized light was collected by silicon photocell and the change of the polarization angle was monitored by digital display with angle sensor.All the results were visually displayed.The elliptically polarized graphics was obtained directly through two ways： instrument fitting and software drawing.The experimental result was in accordance with theoretical calculation.
