| 摘 要： | 在理论和实验上研究了完全偏振光的不同偏振态和光的偏振度对Hanbury Brown-Twiss实验二阶关联函数g(2)的影响.实验中用线偏振光通过1/4波片获得椭圆偏振光,并通过旋转波片实现对完全偏振光偏振态的改变;用两柬振动方向相互垂直,传播方向相同且相位差随机的线偏振光合成部分偏振光,并通过调节一束光的光强实现对合成光偏振度的改变.结果表明:对于完全偏振光,其偏振态的改变对g(2)没有影响;对于不同偏振度P的光源,g(2)为P的二次函数.特殊地,自然光情况下P=0,g(2)的理论最大值为1.5;完全偏振光情况下P=1,g(2)的理论最大值为2.理论与实验符合得较好.

| Abstract: | This article studies,both theoretically and experimentally,how the degree of polarization and the polarization state of polarized light affect the normalized second order correlation g(2) in Hanbury Brown-Twiss experiment.In the experiment,the plane polarized light is changed into elliptically polarized light by passing it through a 1/4 wave plate.By rotating the wave plate,the polarization state of light can be changed.Two beams of light with mutually perpendicular vibration direction,same propagation dire... |
