红外光谱中的新型椭偏法：双参考法
New type of ellipsometry in infrared spectroscopy: The double-reference method
摘要：
我们已经开发出一种概念上新型的椭圆偏振法，它允许通过同时测量相对于真空和另一个参考介质的非偏振法向入射反射率来确定复折射率。由这两个量可以直接得到复光学响应，而不需要Kramers-Kronig变换。由于其在从远红外到软紫外区域的广泛光谱范围内的透明度和大折射率，金刚石可以理想地用作第二参考。与其他椭偏技术相比，实验装置相当简单。
英文摘要：
We have developed a conceptually new type of ellipsometry which allows the determination of the complex refractive index by simultaneously measuring the unpolarized normal-incidence reflectivity relative to the vacuum and to another reference media. From these two quantities the complex optical response can be directly obtained without Kramers-Kronig transformation. Due to its transparency and large refractive index over a broad range of the spectrum, from the far-infrared to the soft ultraviolet region, diamond can be ideally used as a second reference. The experimental arrangement is rather simple compared to other ellipsometric techniques.
