| 摘 要： | 从理论和实验上研究了当部分相干光照射在双缝上时,杨氏双缝干涉实验干涉场中的光谱变化.指出干涉场中的归一化光谱在某些空间点处出现了蓝移,在另外一些空间点处出现了红移,而在这些空间点的中间,光谱分裂为等值的两条,出现了光谱开关现象.发现当观察点从轴上向轴外移动的过程中,在很多空间观察点处都出现了光谱开关现象.此外,研究结果还表明光谱相干度将对光谱的移动和光谱开关现象产生重要的影响.

| Abstract: | The spectral changes of the interference field of a Young's double-slit interference experiment illuminated by partially coherent light were studied both theoretically and experimentally.It shows that the normalized spectrum of the interference field is blue-shifted at some positions and is red-shifted at other positions,and between these positions the normalized spectrum splits into two lines with same height,which is called a spectral switch.It is found that the spectral switch occurs at several observati... |
