Think in the future

Welcome to my page! I am Chao (Oliver) Xu, a Senior System Engineer at BOCHU in Shanghai. I develop industrial optical coherence tomography (OCT) systems for real-time laser-welding depth monitoring. My work on UltraOCT and next-generation OCT platforms spans optical-system architecture, raw-signal processing, self-interference artifact analysis, hardware and component evaluation, algorithm validation, system-level testing, and field troubleshooting.

Before joining BOCHU, I was a Postdoctoral Fellow and PhD researcher in Biomedical Engineering at The Chinese University of Hong Kong. My research covered OCT, fiber optics, biomedical imaging, OCT endoscopy, and translational medical-device development, including miniature high-resolution endoscopes for neuroimaging and other preclinical and clinical applications.

I received my PhD from The Chinese University of Hong Kong, my MSc in Optics from the University of Chinese Academy of Sciences, and my BE in Optical Sciences and Engineering from Zhejiang University. I am interested in turning advanced optical physics into OCT systems that are reliable, manufacturable, and valuable in real-world industrial and medical applications.
