| 中文摘要: |
| 古斯-汉欣位移是一种反常的光学现象，当一束有限横截面积的光束在不同折射率的两种介质界面发生全反射时将产生一个侧向的位移，也就是说反射点和入射点不在同一点，此位移就称为古斯-汉欣（Goos-Hänchen，GH）位移。通过介绍近年来国内外的研究发展历程，研究了GH位移的数学推导、量子散射以及其在位移传感器、溶液浓度变化的测量等方面的实际应用。 |
| 英文摘要: |
| The Goos-Hänchen shift is an abnormal optical phenomenon. When a beam of light having finite section is totally reflected on an interface of two mediums having different index of refraction, there will be a lateral displacement, that is to say the reflected point and incident point will not be at the same position, and the lateral displacement is referred as the Goos-Hänchen (GH) shift. Through the introduction of research progress of GH shift in recent years both at home and abroad, the mathematical calculation of GH shift, its quantum scattering analog and its application such as displacement sensor and solution concentration change measurement were respectively studied. |
