Optical coherence tomography (OCT) has been applied to the study of the microscopic deformation of biological tissue under compressive stress. We describe the hardware and theory of operation of an OCT elastography system that measures internal displacements as small as a few micrometers by using 2D cross-correlation speckle tracking. Results obtained from gelatin scattering models, pork meat, and intact skin suggest possible medical applications of the technique.
光学相干断层扫描（OCT）已被应用于研究生物组织在压缩应力下的微观变形。我们描述了一种OCT弹性成像系统的硬件和操作原理，该系统通过使用二维互相关散斑跟踪来测量小至几微米的内部位移。从明胶散射模型、猪肉和完整皮肤获得的结果表明了该技术可能的医学应用。
