Chapter 1. The development of Optical Coherence Tomography 为什么1300 nm的OCT系统是最常用的？ Why Ophthamology and Cardiovascular OCT are two most commercial applications? OCT技术的发展与激光器技术的发展有什么关联？ SS-OCT相较于SD-OCT的优缺点是什么？更适用于什么应用？眼科？心血管？ How cardiovascular OCT is performed in the surgery room? 心血管OCT的市场发展历程、未来展望是怎么样的？
昨天上午，我和朋友去看了《奥本海默》，有一种作为科学家的无力感。在政治权力面前，科学家的存在确实是很渺小（’like a little crying baby’）。
