Optical coherence tomography (OCT) images are frequently interpreted in terms of layers (for example, of tissue) with the boundary defined by a change in refractive index. Real boundaries are rough compared with the wavelength of light, and in this paper we show that this roughness has to be taken into account in interpreting the images. We give an example of the same OCT image obtained from two quite different objects, one smooth compared to the optical wavelength, and the other rough.
光学相干断层扫描（OCT）图像通常根据层（例如组织层）来解释，其边界由折射率的变化定义。实际边界与光的波长相比是粗糙的，在本文中我们表明，在解释图像时必须考虑这种粗糙度。我们给出了从两个截然不同的物体获得的相同OCT图像的示例，其中一个与光波长相比是光滑的，另一个是粗糙的。
